Since forming in 2011, Moonsville Collective have whipped up a raw, rootsy storm of Americana, driving each song forward with a mix of mandolin, banjo, slide guitar, drums, harmonica and fiddle. They play community music. The table is large — the group has seven members, after all, including two generations from the same family — and the harvest is plenty, with the band encouraging their fans to join the party and break bread with them. Born out of a string of old-time jam sessions and songwriting circles in Southern California, Moonsville Collective have held on to that communal spirit, making big-sounding music for a community that is continually growing.
