Grammy Award-winning blues/roots singer, guitarist, pianist, Taj Mahal — an American music veteran of more than 40 years with a massive catalog of songs — returns to Charleston with his own backing combo for an intimate concert. The trio includes bassist Bill Rich, who’s played with Taj off and on since 1969, and drummer Kester Smith, who’s been keeping time with the guys since the late ’70s. Taj signed on with the Heads Up International label in 2008 with the worldwide release of Maestro: Celebrating 40 Years. They hit the stage at 8:30 p.m. The Beebos play bluegrass on the deck at 5 p.m.
