Feature Performers: Acme Bluegrass Opening Performers: Mark Gillick, Kari & The Cosmos. Acme Rose is a Colorado Springs band that loves to perform high energy, hard driving acoustic entertainment. Local icon John Ramsey on banjo, transplanted native Les Irvin on mandolin, and New Mexico transplants Sebie and Tracy Denson on bass and guitar, this four piece sings and plays with the spirit of true hillbillies. Here lately, you'll find a fiddler joining in the fray from time to time. The band plays a music mix of traditional and contemporary bluegrass with some diversity from artists like Chuck Berry, Bob Dylan and, of course, the king-Elvis. They've also added some new songs from such bluegrass greats as the Pogues.
