Storch famously got his start as a one-time member of The Roots in their early years (he played and cowrote tracks on The Roots' independent label debut, 1993's Organix), who left the band by 1995 for fame, fortune, and the gossip pages. One of Storch's first big tracks, "Lean Back," a 2004 smash with Fat Joe and Remy Ma, will get a live airing as part of Thought's Live Mixtape, along with "many other surprise tracks and additional unannounced guests," says Trotter. "That's what makes a Roots Picnic great – the performances we have planned and the ones that just happen."
