In continuation of the celebration of their 25th anniversaryThe String Cheese Incident are gearing up for their annual three-night Red Rock Amphitheatre run in Morrison, CO, set to go down on July 19th, 20th, and 21st.

Due to scheduling conflicts with The Rolling Stones‘ recent rescheduled tour, Karl Denson and his band The Greyboy Allstars will no longer able to support SCI on Friday, July 19th. Funk guitarist and frequent Vulpeck collaborator Cory Wong will take The Greyboy Allstars’ spot, marking his debut Red Rocks performance with his solo outfit.

As originally planned, on Saturday, SCI will team up with Keller Williams to celebrate the 20th anniversary of Keller’s 1999 Breathe album, which will be played in its entirety. On Sunday, the Del McCoury Band will open up the evening. Del recently celebrated his 80th birthday on February 1st, and SCI notes that they will “help Del ring in 80 years of bluegrass royalty”.
