Liver is a live album by Steve Taylor, released in 1995.
 Its contents cover all of Taylor's career, including his time with Chagall Guevara.
Steve Taylor & The Perfect Foil is an American alternative rock supergroup formed in 2010 by singer Steve Taylor with drummer Peter Furler (Newsboys, Peter Furler Band), guitarist Jimmy Abegg (Vector, A Ragamuffin Band), and bassist John Mark Painter (Fleming and John).
 Taylor formerly saw success as a new wave singer during the 1980s and early 1990s, and also fronted the short-lived band Chagall Guevara.
 However, by the mid-1990s he abandoned performing music and transitioned into work as a record producer, songwriter, and film-maker.
 In 2010 Taylor, who was frustrated at the slow pace of his fundraiser for his feature film "Blue Like Jazz", collaborated with Furler, Abegg, and Painter to record the song "A Life Preserved" for the film's soundtrack, and began recording other material.
 Taylor, Abegg, and Painter then featured on the Peter Furler song "Closer", under the name "Steve Taylor & Some Other Band", on Furler's album "On Fire".
 With those collaborations as a starting point, Taylor relaunched his career as a performing musician, and the lineup was branded as Steve Taylor & The Perfect Foil.
 The group released a studio album entitled "Goliath" on November 18, 2014 to critical acclaim and modest commercial success.
 In 2015, Daniel Smith of Danielson, with whom the band had been touring, temporarily joined on in a collaboration touted as Steve Taylor & The Danielson Foil.
 Under this incarnation, the group released the EP "Wow to the Deadness" on February 5, 2016, and toured until February 12.
Roland Stephen "Steve" Taylor (born December 9, 1957), is an American singer, songwriter, record producer, music executive, film maker, and actor.
 A figure in what has come to be known as Christian alternative rock, Taylor enjoyed a successful solo career during the 1980s, and also served in the short-lived group Chagall Guevara.
 In contrast to many Christian musical artists, his songs have often taken aim at other Christians with the use of satirical, sardonic lyrics.
 In 1997, he founded the record label Squint Entertainment, which fueled the careers of artists such as Sixpence None the Richer, Chevelle, and Burlap to Cashmere.
 Despite this success, Taylor was ousted from the label by its parent, Word Entertainment, in 2001.
 He has produced and written for numerous musical acts, one of the most consistent being Newsboys.
 As a film-maker, Taylor co-wrote, directed, and produced the feature films "Down Under the Big Top", "The Second Chance", and "Blue Like Jazz".
 After a decade and a half of hiatus, Taylor returned to performing music in 2010 as the front-man for Steve Taylor & The Perfect Foil, a supergroup he founded with Peter Furler, Jimmy Abegg, and John Mark Painter.
Chagall Guevara was an American rock band formed in 1989 by solo artist Steve Taylor, guitarists Dave Perkins and Lynn Nichols (from the 1970s Phil Keaggy band), bassist Wade Jaynes, and drummer Mike Mead.
