A Wilhelm Scream 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". The band released 3 rare demotapes under the names of Koen and Smackin' Isiah. Download them below!
