Martin Eric Ain (real name Martin Stricker, born 18 July 1967) is best known for being the former left-handed bassist of the now defunct Swiss extreme metal band Celtic Frost. According to a recent interview, Ain is, in fact, an alias. The official website for Hellhammer launched in 2007 states his birth name as Martin Eric Stricker.
After amassing a small fortune in the 1980s from Celtic Frost's success, he became an entrepreneur and now owns a successful DVD shop and bar in Zurich, called Acapulco. He is also a co-owner of the music club Mascotte, which has become well known for hosting upcoming international bands. Since 2004 he has been the host of the "karaoke from hell" show, taking place every Tuesday night at the Mascotte Club.
He sang the lead vocals for the song "A Dying God Coming Into Human Flesh" on Celtic Frost's final album, Monotheist.
