Shadow Gallery is an American progressive metal band formed in the Lehigh Valley, Pennsylvania during the early 1980s. It was originally called Sorcerer. After changing their name to Shadow Gallery, taken from the graphic novel V for Vendetta by Alan Moore, and recording a short 8-track demo, the band was signed to Magna Carta Records in 1991. Shadow Gallery's eponymous debut was released the following year in Japan and Europe. In mid-2005, Shadow Gallery released their fifth studio album, Room V, on the European-American independent label Inside Out Music.

The band has been compared to contemporary progressive metal bands Dream Theater and Symphony X. The members of Shadow Gallery have also collaborated with other progressive metal bands. Dream Theater's James LaBrie contributed backing vocals to the song "I Believe", which appeared on Shadow Gallery's 1998 album, Tyranny, and in return Shadow Gallery members have contributed to LaBrie's side projects, including MullMuzzler.

Shadow Gallery songs, often in the context of a concept album or story, are frequently long with extended instrumental pieces in the middle. For diversity, their music is heavy at times and mellow at others, sometimes incorporating elements of neoclassical and symphonic metal.

On October 29, 2008, lead singer Mike Baker died of a heart attack at the age of 45.

Sorcerer originally consisted of Mike Baker, Carl Cadden-James, Ron Evans, and John Cooney. The ensemble began as a cover band, particularly interested in covering difficult to play songs by artists such as Yngwie Malmsteen and Rush. In 1985, guitarists Chris Ingles and Brendt Allman joined the band, with Ingles immediately switching to keyboard duties. At this time, Ron Evans departed in order to pursue other musical interests and goals.

After changing their name to Shadow Gallery and recording a short 8 track demo, Mike Varney eventually signed them to Magna Carta records on August 23, 1991, as the label's second contract (the first having been Magellan). The record label's objective had been "..to bring a fresh breath of progressive rock to an audience who was subdued by larger record companies quest for typical commercial music". Impressed with Shadow Gallery's initial demo, Varney suspected the band could help fulfill this objective.

Shadow Gallery's eponymous debut was released the following year in Japan and Europe. However, before the arduous commitments of a supporting tour and a new studio album, the band needed to secure a stable lineup. April 1993 saw the recruitment of guitarist/keyboardist Gary Wehrkamp, originally of the band The Boxtops. Another lineup addition followed in April 1994 with drummer Kevin Soffera. With this new solidified lineup, Shadow Gallery released its second studio recording on July 11, 1995, titled Carved in Stone. However, time constraints and other commitments precluded the band from touring in support of both albums.

Carved in Stone was followed up by their 1998 release, Tyranny with drummer Joe Nevolo replacing Kevin Soffera. The album is a deeply political concept album, with themes including the nature of war and the military-industrial complex. Tyranny is also notable for the contributions made by a number of guest musicians. Beyond James LaBrie's vocal contribution to "I Believe," D. C. Cooper (vocalist of Royal Hunt) contributed vocals to the track "New World Order," and violinist Paul Chou made a guest appearance on the tracks "Spoken Words" and "New World Order," with the former featuring a duet between Mike Baker and Laura Jaeger. Shadow Gallery would return the favor to LaBrie in 1998 when Allman, Cadden-James, Wehrkamp and local musician/songwriter Gary Sloyer appeared on and aided in LaBrie's musical side project, Mullmuzzler. Their debut record, Keep It to Yourself, was released by Magna Carta in the Summer of 1999."
