Tedeschi Trucks Band and Alabama Shakes concluded their four-show joint run last night at Cincinnati, OH’s Riverbend Music Center. Alabama Shakes closed yesterday’s concert and invited Tedeschi Trucks Band principals Susan Tedeschi and Derek Trucks back to the stage during their set for “Time,” a number from this year’s new LP, I Must Be Dreaming.

The sit in capped off a busy week of cross-pollination between the two acts. As previously reported, on Tuesday at the Acrisure Amphitheater in Grand Rapids, MI, Alabama Shakes singer Brittany Howard and Shakes background vocalists Karita Law and Shanay Johnson joined TTB for a pair of Sly Stone tacks. On a night when TTB closed out the festivities, the 15 musicians kicked into “You Can Make It If You Try” from Sly and the Family Stone’s 1969 album Stand! This, before moving into “Everyday People” from the same record.

Tedeschi Trucks Band will perform at Washington, DC’s Wolf Trap tomorrow, with Lukas Nelson opening the night. Meanwhile, Alabama Shakes will appear at Minneapolis, MN’s Surly Brewing Co. the same night with Hannah Cohen rounding out the bill.
