The 10th Annual NedFest is a 3-day outdoor music and microbrew festival with camping located on the shores of Barker Reservoir in the mountains of Nederland, Colorado... only 17 miles west of (3,000 ft. above) Boulder. It happens the weekend before Labor Day weekend in August and the music featured is in the Bluegrass, Jazz, Jamband and World-Beat genres... or moreso, a sound that blends these styles (and others) together. Up to six bands perform each day on one stage, with acoustic 'tweener sets between each band.
