Existing at the intersection of free jazz, acid folk, spoken word and avant garage rock, ESP-Disk opened for business in New York City at the zenith of 60's counter culture. The label's first release was an Esperanto album, giving it the name ESP-Disk, and then released a number of free jazz albums that we would now consider classics. It soon came to champion other similarly less-commercial genres, always giving free reign to the artists. This Guide To includes music from Sun Ra, Albert Ayler, William Burroughs, The Fugs and more.
