Linda Perhacs is an American psychedelic folk singer-songwriter, who released her debut album "Parallelograms" in 1970 to scant notice or sales. The album was rediscovered by record enthusiasts and grew in popularity with the rise of the New Weird America movement and the Internet. It was reissued on CD and 2-LP in 2005, and again in 2008. Native of Mill Valley, California, United States, Linda Perhacs spent many years away from the music industry (mostly spent as dental technician).
