Freestyle Fellowship are a rap group from Los Angeles consisting of rappers Aceyalone, Myka 9, P.E.A.C.E., Self Jupiter and producer J Sumbi. Their vocal techniques focusing on the method of the freestyle, as well as a successful infusion of hip hop and jazz, established the group as forerunners in the sub-genre of jazz rap, and also placed them amongst prominent West Coast underground hip hop acts of the early 1990s like Hieroglyphics, Abstract Rude & Tribe Unique, and The Pharcyde. They are part of a hip hop collective known as Project Blowed.
