Rick and Morty has proven itself a cultural phenomenon many times over. Now, fans of the joyfully nihilistic sci-fi cartoon are taking Rick and Morty fever to a new level with the announcement of the Rick and Morty Musical Ricksperience, a 37-piece orchestra helmed by Ryan Elder, the man behind the show’s score. The Rick and Morty Musical Ricksperience comes as part of the final lineup announcement for the upcoming inaugural Adult Swim Festival, set to take place at ROW DTLA in Los Angeles on October 5th through 7th.

Notes the announcement,

For the first time ever, see composer Ryan Elder (The man behind Rick and Morty’s music) and some very special guests bring your favorite Rick and Morty songs to life in melodic harmony in sync with an episode. There’s going to be an actual orchestra, with trombones and stuff.

The inaugural Adult Swim Festival will showcase more than 24 hours of live entertainment, featuring 42 musical and comedy performers over three days and headlined by Run the Jewels and Mastodon and featuring performances from Dorian Concept, Flying Lotus (in 3-D), Georgia Anne Muldrow, Hannibal Buress, ThundercatT-Pain performing tracks from Freaknik: The MusicalBig FreediaNeko Case, and many more.

Fans will get a unique opportunity to be fully immersed in an Adult Swim experience like no other happening on and around two massive stages. They can take a trip on the DREAM CORP LLC Virtual Reality Eggs, play a round of Rick and Morty Mini Golf, ride a giant Hot Dog Ride, soak in six minutes of air-conditioning in the immersive Meatwad Dome 4D Experience, and climb everyone’s favorite feline on Smack Up My Uvula. Fans far and wide will also enjoy live broadcasts by Adult Swim’s FishCenter & Friends, featuring the best of the streams.
