ESP-Disk is a New York-based record label, founded in 1966 by Bernard Stollman. Though it originally existed to release Esperanto-based music, starting with its second release (Albert Ayler's Spiritual Unity), it became the most important exponent of what is commonly referred to as free jazz. ESP also released recordings by uncommercial underground rock acts like the Fugs, The Godz and Pearls Before Swine. Though it largely ceased releasing records in the 70s, a few new releases have crept out from the label, and it still exists to this day, with nearly its entire catalog still available.
