Timothy “Tim” Peter Lambesis (born November 21, 1980) is an American vocalist, songwriter, musician and producer, better known as the lead singer and founder of metalcore band As I Lay Dying. He’s also a member of Austrian Death Machine, a thrash metal band, which is a parody/tribute to Arnold Schwarzenegger’s films.
Lambesis writes (almost) every lyric to As I Lay Dying songs. Although he only provides unclean vocals nowadays, he used to do clean vocals and play keyboard for the band.
Due to a solicitation of murder, Lambesis was arrested in 2013, resulting in a period of over 5 years without new As I Lay Dying music.
