Guts of a Virgin is the first album by American band Painkiller, a band featuring John Zorn, Bill Laswell and Mick Harris. It contains twelve tracks and was released in 1991 on Toy's Factory in Japan and Earache Records in England.
Harris later recalled the album was recorded during a three-hour session in New York City, and all the songs were entirely improvised and composed in the studio. This recording session also led to Harris's departure from Napalm Death, as working with Zorn and Laswell made him realize he wanted to explore different genres of music.
