Bob Log III, with Little Cuts, Dirty Bird Cabaret. Tractor Tavern, 5213 Ballard Ave. N.W., 789-3599. 9 p.m. $15. When it comes to motorcycle helmet- and spandex suit-wearing one-man bands, Bob Log III is the best in America. Making a name for himself in the mid-90’s playing with lo-fi blues duo Doo Rag, Log continues to play his skewed, crispy-fried version of the blues on his own. Log’s blown-out vocals and filthy slide guitar playing scream “juke joint you might get stabbed in,” while his goofy personality suggests “hey, this show might sound better from the Chuck E. Cheese ball pit.” And his enthusiasm, showmanship, and just plain out of control presence make for a joyful (if not slightly twisted) down home experience. GREGORY FRANKLINBrad, with Stuck on a Bus. High Dive, 513 N. 36th St., 632-0212. 9 p.m. $12. Seattle’s Brad first gained some spotlight in the early 90’s, due to guitarist Stone Gossard’s other band (a little well-kept secret called Pearl Jam). But Brad was light-years away from the angsty grunge of the day, relying more on mellow 70’s-esque pop and soul. Brad’s songs have a loose, organic feel, with Shawn Smith’s buttery voice gliding over somber and upbeat melodies alike. Even the band’s most rocking numbers have a controlled chaos to them, playing in the pocket rather than beating the listener over the head with screaming riffage. Brad seem to come out of hibernation only every few years, although with the impending release of their fourth album (Best Friends?), this likely won’t be the last we hear of them for a while.
