Started in 1974 as The New Expression Folk Music Study Center by three San Diego musicians, MCCM now offers performance workshops, group and private lessons, weekly jam sessions, and free community concerts on a quarterly basis. Services are provided on a low-cost, sliding-scale basis in some of San Diego's most ethnically diverse and economically disadvantaged neighborhoods to community members who would not otherwise have the opportunity to learn to play an instrument, sing and play in a group, or perform on stage.
