Terry Garthwaite is an American guitarist and vocalist best known as a founding member of Joy of Cooking, the Berkeley-based ensemble that emerged from the late 1960s rock scene. Co-leading the group alongside pianist Toni Brown, Garthwaite helped shape the band's distinctive fusion of rock, folk, blues, and jazz—a pioneering sound that stood out in the early 1970s landscape. The group's 1971 single "Brownsville" became a minor hit, showcasing their ability to blend multiple genres into accessible, radio-friendly arrangements.
Throughout their tenure on Capitol Records, Joy of Cooking released three studio albums that demonstrated Garthwaite's versatile songwriting and guitar work, establishing her as a notable figure in the rock ensemble movement of the era.
