Beloved duo Big Gigantic will once again bring the noise to the famed Red Rocks Amphitheatre in Morrison, CO, as the group has announced their 5th annual Rowdytown celebration. This year’s performances will take place from September 23-24, and special guests will be announced in the coming days and weeks.

Rowdytown is always quite the fun time, as evidenced by the last four years of Big G’s performances on the Rocks. Last year’s performances included RL Grime, Snails, Thomas Jack, Defunk and more, and past editions have featured theNEWDEAL, The Floozies, Savoy and members of The Motet for a live Big G performance.
