LSU (a.k.a. Lifesavors, Lifesavers, Lifesavers Underground, and L.S. Underground) was a 1980s and 1990s Christian rock band fronted by singer/songwriter Michael Knott. Other members of the original band included Mark Krischak (vocals), Kevin Annis (drums) and Chris Wimber (guitar). Brian Doidge (guitars, bass) and Andrew Carter (guitar) were later members of the band.
Having elements of post-punk and new wave throughout their career, Lifesavers Underground's early material was characterized by somewhat dark atmosphere, and their Shaded Pain era music is reminiscent of the early 1980s British gothic rock style.
Despite inactivity from the LSU moniker in recent years, Michael Knott announced in August 2008 that he has recorded a new L.S. Underground album with Josh Lory, Jim Chaffin from the Crucified, Matt Biggers, Daniel Sonner and others. Knott states that the album is a tribute to returning soldiers and will deal with issues such as post-traumatic stress disorder, and on his website he states that he "feels this is the most important record he has done since 'This Is the Healing'." The expected release date is November 2008.
Several Lifesavors bootlegs have appeared including 3-14-81 and The Nashville Demos from the early 80's. Much like Knott, Krischak has released several projects since the demise of Lifesavors including Generation XXX (2000) and Sci Fi Music Madness (2005).
