Oct. 26 The Wood Brothers w/ Patrick Sweany Waiting Room, 6212 Maple St. 9 p.m., $15, onepercentproductions.com Armed with two voices, a bass and acoustic guitar, The Wood Brothers specialize in delivering raw, unapologetic bluesy folk-rock, oozing with emotive lyrics. Chris Wood is one of the founding members of Medeski, Martin and Wood, a jazz trio formed in 1991. After reveling in moderate success with them, Wood reunited with brother Oliver to explore their love of shared childhood influences — everything from blues to rock. Their 2008 album, Loaded (produced by John Medeski), was released on Blue Note and is subtle enough to make you want to hear it again. It glides in with ease and bursts with organic sounds. Delivering nothing but the best in modern folk, The Wood Brothers are headlining their current U.S. tour. Kicking off in North Carolina, the boys trek to their home state of Colorado before landing in Omaha. If slow, well-constructed folk songs are in order, The Wood Brothers are doing it.
