The John Mayer-fronted incarnation of the Grateful Dead’s legacy finally makes its way to Northeast Ohio tonight. Bobby, Billy and Mickey are along for the ride, representing the actual Dead and joining Mayer, bassist Oteil Burbridge and the ubiquitous Jeff Chimenti on keys. There’s been a lot of hype for this early leg of the summer tour, and we’ve heard some mighty fine stuff on recent soundboard releases. (Check out the Boulder shows That “Althea” is sublime.) Listen: These shows are about mood and time more than anything, about channeling the spirit of eras displaced from the past. You won’t want to miss it. Let the good times roll. (Eric Sandy)
