Vic Chesnutt Tribute and Benefit. Tractor Tavern, 5213 Ballard Ave. N.W., 789-3599. 8 p.m. $10 donation.When Vic Chesnutt passed on Christmas Day of 2009, he left a legacy of arrestingly emotive folk music behind him. Unfortunately, he also left a lot of medical bills along with it, even though the songwriter allegedly paid $800 for health insurance each month. Chesnutt was wheelchair-bound – the tragic consequence of a car accident when he was 18 – and many of his friends and fellow artists attribute his death from what the Los Angeles Times called an “intentional overdose” on muscle relaxants to the stress caused by his mounting debts. To help pay off Chesnutt’s remaining medical bills, Dave Bazan and Damien Jurado will be stopping by to perform, as well as Seattle musicians Erik Howk, Jason Dodson (the Maldives), Ian Moore, Marc Olsen, Mike Dumovich, Anne Marie Ruljancich, Lori Goldston, Erin Jourgensen and Your Heart Breaks, who will all play covers of Chesnutt’s songs in tribute to Vic Chesnutt’s art. After covering expenses, 100% of the proceeds from the show will be donated to offset the bills Chesnutt left behind. SARA BRICKNERFree Energy, with Foreign Born. Chop Suey, 1325 E. Madison St., 324-8005. 8 p.m. $10.Lest anyone fear that DFA is forever marooned on the dance floor, the label’s latest signing is a guitar-worshiping retro-rock band. Solos unfurl in wide ribbons all over the Philly five-piece’s James Murphy-helmed Astralwerks/DFA debut, Stuck On Nothing. Cowbell even rings in the album on the opening theme song, “Free Energy.” Thin Lizzy comparisons are certainly warranted, although nods to Boston and T. Rex wouldn’t be far afield either. It’s still dance music of a sort, only without all the spongy synths and beats. That said, “Dream City” is appropriately spacey, and other tunes betray the ductile skeleton of funk or disco, despite being so couched in yesteryear’s AM rock radio. Guided by singer Paul Sprangers and guitarist Scott Wells – who did time together in the Minneapolis band Hockey Night – Free Energy boasts some of the most carefree vocals and carousing hooks since the Strokes.
