String Cheese Incident keyboardist Kyle Hollingsworth has assembled an impressive group of musicians to join him for two dates in early September. On September 8 at the Boulder Theater Hollingsworth will be joined by George Porter Jr., Karl Denson, Eric Krasno, Neil Symonette & Liza for a show that will mark the 13th anniversary of the Mountain Sun Pub and Brewery. The following afternoon this same collective, sans Liza, will perform in Crested Butte, as part of the KBUT Crested Butte Alpine Jam.
