Brand New War are a punk rock/street punk band from Los Angeles, California who began their career as The God Awfuls.
 As the God Awfuls, their music was described as "pedestrian political punk rock."
 The song, "Watch It Fall", from The God Awfuls album, "Next Stop Armageddon" was featured on the 2005 skateboarding video game Tony Hawk's American Wasteland.
 It was produced by The Greedy Bros. (a.k.a. Blag Dahlia of The Dwarves).
 The God Awfuls appeared in the 2007 documentary "Punk's Not Dead".
 In July 2008, The God Awfuls released 3 new songs on a demo.
 On October 28, 2008, The God Awfuls announced on their MySpace page they had changed their name to Brand New War.
This is a compilation of the and The Desert Sessions releases.
 Queens of the Stone Age later performed "You Think I Ain't Worth a Dollar, But I Feel Like a Millionaire" on their "Songs for the Deaf" album, and "Rickshaw" has often been included in their live set.
 "Like a Drug" has been re-recorded and features on certain special editions of "Lullabies to Paralyze".
 "I'm Dead" was recorded by Kyuss/Queens of the Stone Age bassist Nick Oliveri in an acoustic arrangement and retitled "Day I Die" for the Mondo Generator album "A Drug Problem That Never Existed".
 This pair of sessions featured a wider range of musicians than previous releases, including Dwarves singer Blag Dahlia.
"Time" is the fourth track from the English progressive rock band Pink Floyd's 1973 album "The Dark Side of the Moon", and the only song on the album credited to all four members of the band, though the lyrics were written by Roger Waters.
 It is the final Pink Floyd song credited to all four members and the last to feature Richard Wright on lead vocals until "Wearing the Inside Out" on "The Division Bell".
 This song is about how time can slip by, but many people do not realise it until it is too late.
 Roger Waters got the idea when he realised he was no longer preparing for anything in life, but was right in the middle of it.
 He has described this realisation taking place at ages 28 and 29 in various interviews.
 It is noted for its long introductory passage of clocks chiming and alarms ringing, recorded as a quadrophonic test by Alan Parsons, not specifically for the album.
The Uncontrollable is an acoustic duo made up of Nick Oliveri of Queens of the Stone Age and Blag Dahlia of The Dwarves.
Roger Waters: The Wall is a live album by Roger Waters, a member of Pink Floyd.
