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.
"Sweet Sacrifice" is a song by American rock band Evanescence.
 It was released on May 25, 2007, as the third single from their second studio album, "The Open Door".
 It was written by Amy Lee and Terry Balsamo while the production was handled by Dave Fortman.
 "All That I'm Living For" was initially planned to be the third single, as announced at live concerts and online.
 However, due to requests from the band and fan reaction, Wind-up reconsidered its release and announced that "Sweet Sacrifice" would be the band's third single from "The Open Door".
 Evanescence's lead singer Amy Lee wrote the song about the abusive relationship that inspired all of the songs on the group's debut record "Fallen" (2003).
Michael DeWayne Tait (born May 18, 1966) is a contemporary Christian music artist.
 Michael Tait met Toby McKeehan in 1984 when he was in high school.
 Both Toby and Michael met Kevin Max while attending Liberty University in the late 1980s, and together they formed four-time Grammy winning band DC Talk, with whom Michael Tait has released five acclaimed studio albums.
 Tait is the current lead singer of Newsboys, and one third of Christian rock group DC Talk (though the group has been on hiatus since 2000).
 Tait also has had success in his solo career, founding a band called Tait in 1997.
 He toured as a solo act until 2007.
 He became lead singer of the Christian pop rock band Newsboys in 2009, and though Peter Furler was the lead vocalist on the album "In the Hands of God", Tait provided supporting vocals on the project.
 Aside from singing, Tait is also a self-taught guitar player.
 Tait also has a sister Lynda Randle, who is a Southern Gospel singer.
Not Ashamed is the fourth studio album by Australian CCM band Newsboys, released in 1992.
 The album was the Newsboys' first commercially successful album, with the title track "I'm Not Ashamed" becoming a hit on Christian radio.
 Also, starting with this album, Steve Taylor started co-writing many of the band's songs with Peter Furler.
On Fire is the first studio album released by Australian Christian musician Peter Furler.
 It marks Furler's solo debut after his departure from Newsboys in 2009.
 After some date changes, the album was finally released 21 June 2011.
In the Hands of God is the thirteenth studio album by Christian band Newsboys.
 It was released on May 5, 2009, being the last album the band released before the departure of singer and founding member Peter Furler.
 It also features the return of Jody Davis, after a five-year hiatus, the first album on which keyboard player Jeff Frankenstein took on some production duties, and is the first album to feature any recording with Michael Tait as singer.
 Tait later replaced Furler.
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.
