Zachary "Zak" Stevens (born March 5, 1966), is best known as the former lead vocalist of the band Savatage. He is currently the singer for progressive power metal band Circle II Circle. Stevens is also a drummer and has a degree in psychology but is not, as is often reported, a licensed, practicing psychologist.
Stevens first achieved fame singing for a band called Wicked Witch. However, after Savatage co-founder Jon Oliva stepped down from the fore of the band at the conclusion of their tour in support of Streets: A Rock Opera in 1992 to concentrate on other projects, namely his other band Doctor Butcher and a Broadway-bound musical entitled Romanov, Savatage required a replacement. Jon hand-picked his replacement, who was discovered and introduced to the band by Criss Oliva's best friend and guitar technician Dan Campbell. Criss Oliva, Savatage's lead guitarist, and their long-time producer Paul O'Neill heard demos of Stevens and wanted him to sing for the band. After an initial audition, Stevens was considered to be the right man for the job and joined Savatage in 1993. He first appeared on the album Edge of Thorns. Stevens's vocals were considered to be a departure from that of Jon Oliva, and some Savatage fans prefer to distinguish between the Jon Oliva lead albums and those with Stevens on lead vocals. The album Dead Winter Dead contains lead vocals from both Oliva and Stevens and contains the song "Christmas Eve (Sarajevo 12/24)", which gave rise to and became a hit for the Trans-Siberian Orchestra. In 1996, Stevens appeared along with other Savatage members in the Trans-Siberian Orchestra project. His last album recorded with Savatage was The Wake of Magellan (1997), which some fans consider to be Savatage's best work in the post-1993 Savatage canon.
In 2000, Stevens quit Savatage, citing that he wanted to spend more time with his young family. During the winter of 2001, Zak started his comeback with long-time friend and co-founder of the band, Dan Campbell. His Savatage connections remained evident, as Jon Oliva produced the first Circle II Circle album, Watching in Silence, and guitarist Chris Caffery recorded guitar on some songs. Oliva and Caffery also co-wrote several of the songs on Watching in Silence. In 2003, Stevens's band left Circle II Circle to join Jon Oliva's band Pain. Stevens then hired an all-new band. Circle II Circle has released three additional full-length albums since, 2005's The Middle of Nowhere, Burden of Truth in 2006, and Delusions of Grandeur in 2008. In April 2014 "Ancient Rites of the Moon", the first album of the project Stardust Reverie (Graham Bonnet, Lynn Meredith, Bill Hudson and Melissa Ferlaak), was released. "Mighty Roar" becomes one of Steve's most impressive songs to date.
