David Shaw of The Revivalists joined Galactic during their performance at New York City’s Terminal 5 on Saturday night. Shaw added his soulful sound to a number of songs, taking on a role that has primarily been played by Living Colour’s Corey Glover in recent years. The Revivialists frontman made his first appearance for a three-song stretch that included “Hey Na Na,” Bobby “Blue” Bland’s “Ain’t No Love (In The Heart of the City),” and “You Don’t Know.”

Shaw returned to the stage for another three-songs starting with a crowd-pleasing rendition of The Beatles’ “I Am the Walrus,” which segued into the triumphant “Heart of Steel.” Trombonist Corey Henry got a chance to show off his hip-hop chops as vocalist on “From the Corner to Block,” the title track off Galactic’s 2007 rap-fusion album. The song was originally recorded with the band’s fellow New Orleanian Juvenile. Shaw then came back for “I Got Your Money” and “Better Off Dead” before Henry once again took on vocal duty to lead the band (and the crowd) in an “Ooh Nah Nay.”

However after all this, the highlight of Shaw’s sit in may have come at very end of the night. After coming out for an encore rendition of “Does It Really Make A Difference,” the Revivalists singer led Galactic in an electrifying take on the Led Zeppelin version of Kansas Joe McCoy and Memphis Minnie’s “When The Levee Breaks.”
