Earlier in the week, we reported that Robert Randolph the Dave Matthews Band for a version of Louisiana Bayou at the Post-Gazette Pavilion. Apparently the collaboration was well-received and, for the past two nights, Randolph has joined the Virginia-bred quintet on stage for encore performances of Louisiana Bayou at Columbus, OHs Germain Amphitheatre. Randolph also appeared with the group on perennial guest favorite All Along the Watchtower and its new Stand Up (For It) throughout his two-night stand. Friday Dave Matthews Band will headline Bonnaroo before returning to the Midwest for an appearance in Noblesville, IN. Randolph will appear at Atlantas Midtown Music Festival with his Family Band and Bonnaroo with The Word this weekend.
