Originally formed from an idea that Peter Shapiro had about commissioning original set-break music at the Grateful Dead’s 50th anniversary concerts, Circles Around the Sun delves into post-rock, surf-rock, jazz-funk, and psychedelia. Their recorded output has included collaborations with such diverse luminaries as Joe Russo, Billy Strings and Mikaela Davis. Original instrumentals form the bedrock of the live show, which features vigorous jams. Tonight's show at the Beachland Ballroom begins at 8 p.m. Mikaela Davis and Southern Star open.
