Last night, on Thursday, December 21st, Kyle Hollingsworth of String Cheese Incident surprised attendees at The Post in Boulder, Colorado. For the venue’s Pickin’ At The Post, a monthly jam on the last Thursday of each month that pays tribute to a different artist each session. For this month’s jam, the group of local Colorado musicians was paying tribute to The Rolling Stones when Hollingworth decided to pop in.
