Back in August of 2022, South Park creators Trey Parker and Matt Stone hosted a pair of concerts to celebrate the 25th anniversary of the show at the Red Rocks Amphitheater in Colorado. The setlist included a number of South Park songs mixed in with Ween and Primus tunes, along with a surprise performance from Rush's Geddy Lee and Alex Lifeson of Closer to the Heart with Primus and Matt Stone on drums. The concert was televised and the audio can be found on streaming services, but it will now also be available on vinyl as part of a special Record Store Day release on April 20th. The 3-LP set is pressed on Towelie-Blue vinyl and will be limited to 4000 copies. You can check out all the details, including the full 22-track setlist here, and get a list of participating stores here.
