“Loose Folk” is a community music event hosted by the Harvard Cultural Collaborative (HCC) on the second Sunday of each month. The first of these relaxed jams will be Sunday, March 11, from 3:30 to 5:30 p.m. Musicians and singers are invited to gather at the old library, 7 Fairbank Street, to share songs, harmonies, and fun. Participants will determine what is played and sung without strict boundaries. Anyone from Harvard or elsewhere who enjoys making a joyful sound or listening to others do so, is invited. Suggested donation of $5 per person. Patrons may bring their own refreshments. Visit harvardculture.org for more details on this and other HCC events and programs.
