Penelope Houston (born December 17, 1958 in Los Angeles, California) is an American singer-songwriter best known as the singer for the San Francisco-based punk rock band The Avengers. She was raised in Seattle. In the mid-1970s she attended Fairhaven College in Bellingham, Washington. In 1977, Houston moved to San Francisco, attended the San Francisco Art Institute and shortly thereafter became the lead singer and songwriter for the Avengers. That band released only one album, their eponymous debut in 1983. The album is now out of print, although two retrospective collections are available.
