Doug Demay and Zak Sitter both played guitar in the short-lived band Mopar before dedicating their time to Fat Day.
They have been known to play dressed only in clear cellophane wrap or have vocalist Matt Pakulski locked inside a speaker cabinet for the entire duration of a live show.
Their 1997 tour of the UK and Ireland featured a fifth "member" wearing only a pair of jockey shorts, with a toy saxophone and covered in a substance of the band's choice at every gig.
Their sound on that tour was a mixture of noise, avant-punk and hardcore, frequently giving the impression of a more impenetrable The Fall attempting some of Captain Beefheart's most difficult pieces, arranged by a "The Black Saint And The Sinner Lady"-era Charles Mingus.
