May 27-29. In 2004 the members of this millions-reaping, heap-topping, jam-band juggernaut announced they were breaking up. But after a torturous five years the Vermont band’s legions of “phans” had their prayers answered when the group reunited for three sold-out arena shows in 2009 and decided to keep it going with a tour that included a Bonnaroo headlining slot and a new studio album, the same year’s Joy. As of this writing, day two (May 28) of the group’s three-night stand at Bethel Woods is sold out, so phollowers (sorry) shouldn’t wait to grab tickets. (Byrds leader Roger McGuinn soars May 6; world-folk unit Eileen Ivers & Immigrant Soul arrives May 14.) 7:30pm. $45, $60. Bethel. (800) 745-3000; www.bethelwoodscenter.org.
