Chicago-based hard rock/alt-metal ensemble SOiL found mainstream success in 2001 with the release of their sophomore long-player, Scars, which featured the radio hits "Halo" and "Unreal." Despite enduring various personnel shifts, the band have remained a mainstay of the active rock charts over the years, releasing hard-charging efforts like re.de.fine. (2004), True Self (2006), Picture Perfect (2009), and Whole (2013), with guitarist Adam Zadel and bassist Tim King serving as the group's sole constant members.

SOiL formed in 1997 around the talents of vocalist Ryan McCombs, drummer Tom Schofield, bass player Tim King, and guitarists Adam Zadel and Shaun Glass. They released their debut EP, El Chupacabra!, in 1998, followed by the full-length Throttle Junkies in 1999. Their sophomore release, Scars, found success both nationally and internationally through two strong singles, "Unreal" and "Halo." It was followed in 2001 by an eponymous EP, and later in 2004 with re.de.fine, which included the high-charting title cut. McCombs left the fold that year, eventually joining Drowning Pool. He was replaced by A.J. Cavalier on the band's 2006 debut for DRT, True Self, which was followed by a slew of European festival appearances and U.S. tours with Sevendust, 10 Years, and Godsmack. In 2009, the band released Picture Perfect, heralded by the single "Like It Is." It would serve as the last studio outing with Cavalier behind the mic.

SOiL's next full-length release was the 2012 concert album Re-Live-ing the Scars: In London, recorded the previous year. Album number six, Whole, appeared in 2013, and saw the group reuniting with original vocalist Ryan McCombs. The band's first compilation album, Scream: The Essentials, appeared in 2017, and SOiL issued the Foo Fighters cover "Monkey Wrench" in 2022 to honor the passing of Taylor Hawkins. ~ James Christopher Monger, Rovi
