For those missing live concerts (and who doesn’t) the documentary “Long Live Rock” is your medicine! You can see it at Longliverockmovie.com. It’s a love letter to heavy metal, complete with festivals and a group of fans who were strangers but bonded at concerts. Jonathan McHugh is the director. Concert Promoter Gary Spivack talks about the heartbreaking suicide of Chris Cornell, right before one of Gary’s festivals.
