A Wilhelm Scream

A Wilhelm Scream (abbreviated as AWS, and for short known as Wilhelm or the Scream) is a melodic hardcore band from New Bedford, Massachusetts. Many people have referenced Strung Out, Hot Water Music, Propagandhi, and Strike Anywhere as the band's similar artists. 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.".
