They recorded a 63-song demo called "Crab Society North" and set to work on an album for Johnny Zazula's Megaforce Records. The album, titled "Speak English or Die", was recorded and mixed over three days, and has since been hailed as a landmark album that was among the first to fuse hardcore punk with thrash metal. They toured in support of the album in 1985, opening for Motörhead and The Plasmatics, among others. Their music served as the theme of the 1980s incarnation of MTV's "Headbangers Ball". They planned a follow-up titled "USA For S.O.D.," which was ultimately scrapped and never recorded.
