Following the release of the plainly titled Casette and Casette 2 mixtapes for Stones Throw, prolific LA producer/MC Jonwayne has announced that he will drop the third piece of his trilogy later this month. Breaking the naming convention with the title The Marion Morrison Mixtape, Wayne’s next release will conclude the series with a helping of new tracks, some which are said to feature the talents of Captain Murphy (Flying Lotus’ MC handle), Jeremiah Jae, Zeroh, and Oliver the 2nd. The offering will be available as a free download and limited cassette on July 30, but before then, a stream of “Altitude”—a particularly stoney, jazz-laced cut co-produced alongside Mndsgn—can be streamed below.
