For the better part of two decades, The Schwag has sought to “preserve and perpetuate the vibe and music made popular by The Grateful Dead.” If all goes according to plan, don’t expect a lot of drama within the walls of The Granada, 1020 Mass., tonight. The Schwag is based out of St. Louis and has played all over Missouri and is in the midst of a tour that will take them through Denver and onward to the west coast. Shortly after Grateful Dead frontman Jerry Garcia’s death in 1995, The Schwag took to the road and has compiled a travelogue of more than 2,000 shows in 18 states. The Schwag, which has more than 200 songs to choose from, operates without set lists much like The Dead did. Tickets are $8 in advance and doors open at 9 p.m. This is an 18 and older show.
