Yesterday we reported that Keller Williams performed with Umphreys McGee Friday while in San Francisco. As we also reported, Williams was in town sharing a bill with Michael Franti and Spearhead at San Franciscos Warfield. In addition to his own set, Williams joined Spearhead for Living Room during its spot. On Sunday Williams shared a bill with Spearhead once again at Lake Tahoe, NVs Montbleu Resort Casino & Spa. On that night Franti joined Williams for the new song Ninja, which the pair recorded for Williams new album Dreams. Williams also sat in with Spearhead for Stay Human, a Franti song he has covered on several occasions. Keller Williams will appear at Buffalo, NYs The Town Ballroom tomorrow.
