Adult Swim, a Cartoon Network progamming bloc, has announced its first and own festival. The event will take place next October, from 5th to 7th, at the Row DTLA in Los Angeles, California.

Acts announced for the inaugural festival include Run The Jewels, Flying Lotus (in 3D), Neko Case, Wavves, Hannibal Buress, Zola Jesus, Mastodon, Thundercat, Big Freedia, Code Orange and many more.

However, the most surprising act announced is the Rick and Morty Musical Experience. This will be a live concert featuring a 37 piece orchestra and several guests. Among them you can expect that Chad Van Gaalen and Chaos Chaos will join in as both are announced in the general lineup.

T-Pain will also come up on stage to perform songs from his TV special Freeknik: The Musical. Passes and single day tickets are already on sale.
