Initially an instrumental improvisation group, American indie rock band Unrest (Mark Robinson, Phil Krauth and Bridget Cross) rose to prominence in the early 1990s for their avant-garde pop music, before disbanding after the release of their final, sublime album on 4AD in 1993: 'Perfect Teeth'. To celebrate the 30th anniversary of 'Perfect Teeth', 4AD is releasing a remastered version of the album on vinyl and as a double CD, the latter including the original tracklisting plus the bonus 'Extra Teeth', compiling rarities and alternative versions.
