Daniel Johnston's final tour is, first and foremost, for him: The home-recording curio-turned-icon has given over more of himself than rightfully should be asked of any artist in any medium, and he's concluding his performing career in triumph, a nightmarish story in micro that looks more and more like an American dream in macro. It's also for his audience, who after 30 years of often-awestruck, sometimes-discomfiting fandom, get to witness one final rambling show and wish the rambler well. Finally, it's for the players playing alongside him, the dozens of musicians in each of his 11 final stops who will profess their love for Johnston and his songs by comprising his backing band and curating the compositions that meant the most to them — a soul-scraping mishmash of ideas as diverse as the people deciding on them (in various cities, Mike Watt, Jeff Tweedy, Cass McCombs, Ben Lee, Maria Taylor and Guy Blakeslee, as well as members of Built to Spill, Fugazi, Beirut, Silversun Pickups and others). The thread that connects them all to Johnston is alternative rock — lending this gig, already the tour's first step, even more significance, as it pairs the lo-fi legend with the religiously in-sync Preservation All-Stars. Expect a set list like no other. The documentary The Devil and Daniel Johnston screens at 7 p.m. Tickets $32.50-$52.50.
