Peter Andrew Furler (born 8 September 1966) is an Australian musician, songwriter, producer and record executive, best known as the co-founder and former lead vocalist of the Christian rock band Newsboys.
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.

 Tait later replaced Furler.
