Greensky Bluegrass closed out a three night run at the Ogden in Denver with a slew of special guests, including Umphrey’s McGee’s Joel Cummins, Eric Krasno, Roosevelt Collier and American Babies, who opened the show.

The sit-ins started early on as Collier and Cummins, who both participated in the Colorado Get Down along with Bill Nershi and others, joined in on the opening numbers “Working On a Building” and “Lose My Way.” To close the first set, Krasno added guitar to “Ain’t No Bread in the Breadbox.”

For the first of two encores, Greensky’s Dave Bruzza took a turn on the drum kit for “Old Barns” as American Babies’ Tom Hamilton joined in on guitar. Then, Hamilton and American Babies bandmates Al Smith and Justin Mazer came out for a cover of Grateful Dead’s “Eyes of the World,” which brought the first encore to a close. Greensky returned for a second encore of “Drink Up and Go Home.”
