The Marleys want to jam it with you Friday. Damian “Jr. Gong” Marley and Stephen Marley are no strangers to Red Rocks Amphitheatre, but when they stop by the venue on Friday, June 28, there will be a new element to their concert. The Colorado Symphony will be jamming behind the two Marleys, who will perform a mix of original material and iconic songs by their father, Bob Marley.
