Prior to joining Helloween, Kiske sang with the German band Ill Prophecy at the age of 17. The band recorded a demo, but it was never released commercially.
At the age of eighteen, Kiske was asked to join the German power metal band Helloween, which was fronted by singer/guitarist Kai Hansen. Hansen had some difficulties being both the lead guitarist and lead vocalist, and it was decided that a new vocalist would be needed. Kiske rejected Helloween's first offer, because he disliked the sound of the band's Walls of Jericho album, but accepted the second and joined Helloween in late 1986. Michael's first album with the band was 1987's Keeper of the Seven Keys Part I, widely considered to be one of Helloween's best albums and a milestone in the creation of the power metal genre. The album's worldwide success enabled the band to embark on an extensive world tour and perform at famous festivals such as Monsters of Rock. Helloween went on to release Keeper of the Seven Keys Part II in 1988, which went gold in Germany and brought even more success than its predecessor. The Keeper of the Seven Keys albums proved to be highly influential and aided in the formation of a new wave of European power metal bands, such as Blind Guardian, Stratovarius, HammerFall and Edguy.
After the completion of the band's 1988 headlining tour, the album Live in the UK was released, while Kai Hansen left the band and was replaced by guitarist Roland Grapow. Legal disputes with their record company, prevented Helloween from releasing new material until 1991's Pink Bubbles Go Ape, which was followed by 1993's Chameleon. These two albums saw the band moving away from their power metal roots and experimenting with different sounds. Both Pink Bubbles Go Ape and Chameleon were commercial failures and resulted in Kiske leaving Helloween. Kiske was fired from the band in 1993, reportedly for personal reasons. He was replaced by Pink Cream 69's Andi Deris, who has remained with Helloween ever since.
Kiske was rumored to be Bruce Dickinson's replacement, after he departed from Iron Maiden in 1993, but the position was filled by Blaze Bayley.
In 2016, it was announced that Michael Kiske would join Helloween, together with Kai Hansen, for a reunion tour that would take place during 2017 and 2018.
On August 16, 1996, three years after leaving Helloween, Kiske released his first solo album, Instant Clarity. The album featured guest appearances by Adrian Smith of Iron Maiden, Kai Hansen and Ciriaco Taraxes and contained songs in a wide variety of styles. A music video for the ballad "Always", dedicated to deceased Helloween drummer Ingo Schwichtenberg, was filmed and produced in New York City. Instant Clarity was reissued in 2006 with the addition of 4 bonus tracks. During the same year he also wrote a book, 'Kunst Und Materialismus', which is only available in German.
His second solo album, Readiness to Sacrifice, was released in Korea and Japan in 1999, and in Europe in 2001. The music on the album featured Michael moving completely away from his heavy metal roots and even contained two symphonic songs.
In 2003, out of desire to make rock music again, Kiske formed a project, named SupaRed. They released a self-titled album in January 2003. This album had a modern rock sound and a song structure, distinct from both his solo albums and the heavy metal sound of Helloween. The project was under promoted and unsuccessful and he dissolved the band.
In 2006, Michael Kiske released his third full-length solo album under the name of Kiske. The album contained songs in a mellow, acoustic singer-songwriter style and was a step away from the sound of his previous solo albums. According to Michael "It's a healthy-careless and musically free album. I am very proud of this record because it is a true statement from myself".
In 2008, Kiske released his fourth solo work, entitled Past in Different Ways. The album contained acoustic re-arrangements of his old Helloween material and one new song. According to Kiske the album "on one hand shows that I don't reject my past just because I'm a different person today, and on the other hand it can maybe give people who were part of that past a different view at those songs".
In 2000, Tobias Sammet (vocalist of the band Edguy) asked Kiske to participate in the rock opera project Avantasia. Michael agreed to sing on the project, in the role of Lugaid Vandroiy, but only under the nickname of Ernie. The nickname was printed on the back of the first Avantasia release, The Metal Opera, but not on the sequel, The Metal Opera Part II, where he was featured under his real name. Michael said in interviews that, at that time, he did not want people to link him to heavy metal anymore. He had a main role in the concept of the Metal Opera albums and performed on the songs "Reach Out for the Light", "Breaking Away", "Farewell", "Avantasia", "The Tower", "The Seven Angels" and "No Return".
During 2007, he recorded guest vocals for two Avantasia tracks; "Promised Land" and "Lost in Space [Extended Version]", both of which appeared on the Lost in Space Part I & II compilation album ("Promised Land" was also featured on the EP Lost in Space Part II).
In 2008, Michael took part in the Avantasia album The Scarecrow, singing lead on the track "Shelter From The Rain" and backing on the title track and on "What Kind of Love".
During 2010, Kiske performed on the Avantasia albums The Wicked Symphony and Angel of Babylon, singing on the tracks "Wastelands", "Runaway Train" and "Stargazers". Between November and December, he also took part in "The Metal Opera Comes to Town Tour", sharing the stage with Tobias Sammet, Kai Hansen, Jorn Lande, Bob Catley, Amanda Somerville, Sascha Paeth, and Oliver Hartmann among others.
On August 6, 2011, Michael performed with Avantasia at the Wacken Open Air Festival.
During 2013, Kiske took part in the Avantasia album The Mystery of Time, singing on the songs "Where Clock Hands Freeze", "Savior in the Clockwork" and "Dweller in a Dream". Between April and August, he also participated on "The Mystery World Tour", which included 10 European festival appearances and 3-hour long shows in South America, Japan, Russia and Europe.
On August 2, 2014, Michael performed with Avantasia at the Wacken Open Air festival once again.
In 2016, Kiske participated in the Avantasia album Ghostlights, singing on the songs "Ghostlights", "Unchain The Light" and on the bonus track "Wake Up To The Moon". Between March and August of the same year, he was part of the biggest Avantasia tour, entitled "Ghostlights World Tour", which consisted of more than 40 concerts in Europe, North America, South America, Canada, Japan, Russia and Scandinavia.
In 2005, Kiske took part in the Place Vendome project, on Frontiers Records. Place Vendome was composed of Dennis Ward (bass and production), Kosta Zafiriou (drums) and Uwe Reitenauer (guitars) from the German band Pink Cream 69, Gunther Werno (keyboards) from the band Vanden Plas and Kiske on vocals. The project's debut album, Place Vendome, was a blend of melodic hard rock and AOR (comparable to the sound of bands such as Foreigner or Journey) and the majority of the songwriting was provided by Dennis Ward.
In 2009, the Place Vendome project released its second album entitled Streets of Fire. A video was filmed for the song "My Guardian Angel", marking Michael's visual return since 1996. The songwriting for the second album was provided by musicians Magnus Karlsson (Primal Fear), Torsti Spoof (Leverage), Ronny Milianowicz (Saint Deamon) and Robert Sall (Work of Art).
In 2013, Frontiers Records released Place Vendome's third album entitled Thunder in the Distance. A video was filmed for the song "Talk To Me". The songwriting for this release was provided by musicians Alessandro Del Vecchio (Hardline), Timo Tolkki (ex-Stratovarius), Brett Jones, Tommy Denander (Radioactive), Magnus Karlsson (Primal Fear), Sören Kronqvist (Sunstorm), Roberto Tiranti and Andrea Cantarelli (Labyrinth).
In 2017, the Place Vendome project released its fourth album entitled Close to the Sun.

The self-titled debut album was released on September 24, 2010. Two videos were filmed for the songs "Silence" and "If I Had A Wish", enabling most of the participants to actually meet in person.
The second Kiske/Somerville album entitled City of Heroes was released on April 17, 2015. Mat Sinner, Magnus Karlsson and Veronika Lukesova handled the instrumentation, while Jacob Hansen and Sinner were in charge of the production. Two music videos were filmed for the songs "City Of Heroes" and "Walk On Water".
On November 10, 2009, Michael formed the band Unisonic together with Dennis Ward, Kosta Zafiriou and Mandy Meyer. Unisonic began a short tour in June 2010, playing some warm-up shows in Germany and performing at Sweden Rock Festival and Masters of Rock Festival as well.
