From 1976 to 1979, while living in Los Angeles, Serry played piano and keyboards on motion picture and television soundtracks (e.g., The Stunt Man, Vegas). From 1981 to 1987, still in Los Angeles, he composed soundtracks for numerous documentary and corporate films, most of them produced by Armand Hammer Productions (a division of Occidental Petroleum) and many of which received Cine Golden Eagle awards (e.g., 'From the Garden of the Middle Kingdom', 1982). In 1983, he toured in the U.S. as pianist with Doc Severinsen's quintet, Xebron. From 1983 to 1985, Serry composed the music for the Bard Productions videos of the Shakespeare plays, 'The Tempest' (starring Efrem Zimbalist, Jr.), 'Othello' (William Marshall, Jenny Agutter) and Antony and Cleopatra (Lynn Redgrave, Timothy Dalton, Bravo Channel). In 1979, Serry was commissioned, by marimba soloist Leigh Howard Stevens, to compose a work for solo marimba. The result, 'Rhapsody for Marimba' (aka "Night Rhapsody"), was premiered by Stevens that year at Town Hall, New York City. In 1985, Serry was commissioned, by percussion soloist Steve Houghton, to compose the 'Concerto for Percussion Brass and Percussion', which was premiered at 1985 Percussive Arts Society (PAS) International Convention and for which Serry was awarded Third Prize in the 1985 PAS competition. In 1986, he revised his work 'Intrusions (for 10 percussionists)' for a performance at the Aspen Music Festival (Jonathan Haas, conductor). In 1987, he was again commissioned by Leigh Howard Stevens, this time to compose the 'Concerto for Marimba and Wind Ensemble' which was premiered at the Kennedy Center with Stevens as soloist and the Madison University Wind Ensemble. In 1988, 'Intrusions' was performed at Alice Tully Hall, Lincoln Center, by the Juilliard Percussion Ensemble with Roland Kohloff conducting. During 1988, Serry arranged several works of Gabrieli for the Canadian Brass, including for their album, Gabrieli/Monteverdi (1989 Sony/CBS). Serry played principal percussion in a concert of the Bartók Sonata for Two Pianos and Percussion (California Chamber Symphony, Los Angeles, 1985) along with Gordon Gottlieb and pianists John and Antoinette Perry. During his years based in Los Angeles (1976–1988), Serry played piano at numerous jazz venues, including The Light House, Donte's, The Baked Potato, Carmello's and the Laguna Beach Jazz Festival.
From 1988 to 1991, Serry was Associate Professor of Music and Director of Jazz at the University of South Carolina, Columbia. While there, he instituted several new courses and revised the curriculum for the bachelor's and master's degrees with jazz emphasis. He also formed and conducted concerts of a jazz and studio orchestra, and produced semi-annual jazz festivals with guest artists, including Marian McPartland, Bill Watrous, Bob Sheppard and others. (Saxophonist Chris Potter, who was then a high school student, participated in the festival concerts and also played in Serry's quartet.)
Serry moved back to New York City in 1991. There he performed with his quartet at numerous jazz venues, including The Blue Note, Birdland, Visiones, Steinway Hall and others. Members of his groups included drummers John Riley and Marvin 'Smitty' Smith, saxophonists Gerry Niewood, Ralph Bowen and Ted Nash, bassists Anthony Jackson and Tom Brigandi and percussionist Gordon Gottlieb. During the 1990s, Serry also composed music for television commercials (e.g., for Grey Advertising). He also played the piano/keyboards and percussion, in several Broadway shows (e.g., 'Saturday Night Fever', 'Cats' and 'Les Miserables') and conducted at Radio City Music Hall. He was Music Director and pianist for the Gateway Playhouse production of the Broadway jazz musical, 'Swing', featuring the music of Duke Ellington, Glenn Miller and others. In 1992, Serry played percussion on Stravinsky's 'Les noces' at Lincoln Center, conducted by Robert Kraft (released on the Musicmasters CD, 'Stravinsky, the Composer', Vol. II). In 2002/3, Serry toured on piano/keyboards with several shows, including a U.S. tour of 'Saturday Night Fever' and European tours of 'Fame' and 'Grease', for which he was Assistant Music Director.
In 2004, Serry moved to London where he formed a quartet with Dave O'Higgins saxophone, Mark Mondesir drums and, variously Mike Mondesir or Sam Burgess on bass. The group played several times a year at The 606 Club (in Chelsea), as well as at other venues. In 2006, Serry recorded the album, 'The Shift' with that quartet, but it was not until 2013 that 'The Shift' (SPCo Records) was released, after a remix in Bologna, Italy. Also while living in London, Serry played a solo and duo piano concert, in 2005, at Covent Garden (Floral Hall) with pianist Julian Joseph. The concert was broadcast by BBC Radio 3 on 'Jazz Legends Live', and was the second 'Jazz Legends' program done by BBC Radio 3 on Serry, the first having been in 2004. Along with these activities, Serry taught at the Royal Academy of Music (Autumn 2004) and played keyboards in the London production (2005) and UK tour (2006) of 'Saturday Night Fever'. In addition, he played piano with Patti Austin, the BBC Big Band, Kyle Eastwood and The 606 Big Band.
For part of 2006 and most of 2007, Serry was in Valencia, Spain, working on a book and playing only a few concerts (e.g., at Conservatorio de Musica Josep Climent, Oliva). In early 2008, Serry toured the Czech Republic playing his compositions with a group of Prague musicians organized by guitarist Adam Tvrdy. Afterwards, he played in several Prague jazz venues (e.g., Reduta Theatre, Agharta) with his own and other jazz groups. Since the start of 2009, Serry has been performing throughout Italy, primarily in Bologna and Emilia-Romagna. His current trio is with Davide Garattoni bass and Bruno Farinelli drums. The trio focuses on playing spontaneously reconstructed versions of Serry's compositions from 'The Shift' and other albums. In 2009, Serry was commissioned by an international consortium of marimba soloists, organized by Ji Hye Jung, to write another solo work for marimba. The work, 'Groundlines', was premiered by Ji Hye Jung at the Percussive Arts Society International Convention 2010.
In his teens, Serry studied percussion with Juilliard instructor Gordon Gottlieb and performed the Darius Milhaud Percussion and Paul Creston Marimba Concertos, the latter on a European tour with the Long Island Youth Orchestra (Summer 1973). In 1975, while a student at the Eastman School of Music, Serry was awarded Best Pianist, Best Composer-Arranger (Combo) and, as part of the group Auracle (then called Inner Vision), Best Combo in the 1975 Notre Dame Jazz Festival. The judges were Sonny Rollins and Jack DeJohnette, among others. Auracle was later signed to Chrysalis Records and recorded 'Glider' (1978) on which Serry played piano and keyboards and for which he composed four of the compositions. The album was co-produced by Miles Davis' producer, Teo Macero, and the group performed at the 1978 Montreux Jazz Festival. In 1980, Serry's first published classical works were entered into the Studio 4 catalogue, including 'Conversations for Timpani Duo', 'Duet for Percussion and Keyboards' and later (1988), 'Therapy' (for multiple percussion soloist). 'Rhapsody for Marimba' ("Night Rhapsody") was published by Marimba Productions in 1980.
Academic career (as educator and in education): Serry has taught classes, ensembles, lessons, seminars and workshops at several schools of music. He coached percussion ensembles at Peabody Conservatory (1986, Jonathan Haas conductor) and at The Juilliard School (1988, Roland Kohloff, conductor) for performances of his composition, 'Intrusions'. He taught a workshop on his compositions at the Musicians Institute (Los Angeles, 1982). He completed two artist residencies at Wichita State University, one in 1985 in which he coached a student ensemble on his composition, 'Concerto for Percussion Brass and Percussion', and played a jazz concert as pianist/composer with Rufus Reid bass and Steve Houghton drums; the other in 1996 in which he gave a lecture on the music business and his jazz compositions, and taught jazz piano and jazz combo. In 1987, he coached the University of Wisconsin-Whitewater wind ensemble on his 'Concerto for Marimba and Wind Ensemble' and also gave a lecture on that composition. Serry taught classes in jazz theory, arranging, music electronics/MIDI, film scoring and jazz combo at University of South Carolina-Columbia (1988–91). From 1994 to 1996, he taught percussion at Jersey City State College. During the 1990s, he was a guest lecturer on the music business at CUNY (Manhattan) and Queens College, a substitute teacher (jazz improvisation) at NYU and coached the Brooklyn College percussion ensemble on 'Intrusions' (Morris Lang, conductor). In the UK, he taught a course in jazz combo at the Royal Academy in 2004/5 and gave a lecture on his jazz compositions at Cardiff University in 2005. In 2011/12, he taught a course in jazz improvisation at Music Academy 2000 in Bologna, Italy. Serry has BM (with Distinction) and MM degrees from the Eastman School of Music (Professors Bill Dobbins, Chuck Mangione, John Beck, and Rayburn Wright; lessons with Marian McPartland; workshops and concerts including playing drums with Keith Jarrett and piano with Joe Farrell and Bill Watrous).
