We definitely didn’t have a vocal warmup with Jay-Z and Jazmine Sullivan on our Roots Picnic bingo card. Jay-Z brought out Jazmine Sullivan during his headlining set at Roots Picnic 2026, and the pair had the crowd participating in an impromptu vocal exercise before diving into the music. #JazmineSullivan #jayz #rootspicnic #rootspicnic2026 #livemusic
