A Wilhelm Scream is a punk rock band from New Bedford, Massachusetts, United States. Their name is a reference to the Wilhelm scream, a famous stock sound effect which mainly is used in films. The band previously went by the names Smackin' Isaiah, Koen and Adam's Crack, though the former was the only name to be used in any major release. The reason for the name changes "from Koen to Smackin' Isaiah to A Wilhelm Scream was really a matter of them adding new members, and progressing/maturing as a band." Early years (1992 - 2000) In 1993, drummer Trevor Reilly, guitarist John Carvalho and bassist Jonathan Teves formed the band Adam's Crack and recorded a Nirvana-inspired demo cassette.
