Leaving the End Open is the third studio album by the American rock group Hardline. This is their first album since 2002's II. The new line up for the album features two new band members, Jamie Brown on bass guitar and Atma Anur on drums. The album was released on April 17, 2009 in the UK and it was released in the USA on May 2, 2009.
The album was called 'Just Add Water' when it was in the works for seven years, beginning in 2004, but Johnny Gioeli gave the title tentatively while planning a different title. During early development in 2004, Rudy Sarzo was slated to record bass, as suggested by Michael T. Ross, but was unable to contribute due to a busy schedule consisting our touring with Yngwie Malmsteen and Ronnie James Dio. Joey Gioeli had also planned to contribute lyrics and rhythm guitar, but seemingly retired from the music industry to manage the Gioeli brothers' companies full-time. Leaving the End Open is the last of Hardline's albums produced by veteran studio man Bob Burch, as well as featuring keyboardist Michael T. Ross.
Japanese guitarist and video game musician Jun Senoue (from the band Crush 40, which also features Gioeli on vocals) is listed as a special guest in the song "Before This". He is credited for the guitar solo.
A Japanese bonus edition of the album was released and it contains a remix of the song "She Sleeps in Madness".
Eight known songs were to be included on the album, as revealed in 2006: "My Heart," "Hold On," a demo originally recorded by Hardline's predecessor, Brunette, "Hole in My Head," "Save Me," "Falling Rain," "Looking at the World," "I Surrender," and "What If." "Hole In My Head" is the only aforementioned song that is confirmed to have been included on the final release.
