Flowmotion is a band you simply have to see live to fully understand. In concert, their natural blend of Screaming Trees-like melodi-grunge and Southern twang explodes into a wailing mass of guitar solos and extended funk riffage that you don’t necessarily have to be paying full attention to to enjoy, which is good because it’s nearly impossible not to get lost in the ass-shakeability of the set. That said, this night at the Tractor is a Halloween show for which they will be playing The Beatles’ Rubber Soul in its entirety. Crazy? I say ballsy. The band has entertained at countless original shows–even their own festival (see: Summer Meltdown)–so why not get wacky with RS? Bouncier tracks like “The Word” and “I’m Looking Through You” can swing on their own, but it should be interesting to see how they spice things up when going gets mundane. With Current Swell, Aaron Daniel. TODD HAMM
