New Orleans quartet MuteMath is one of the few currently commercially viable rock bands that truly seems undefinable. Though the group creates the kind of melodies that are punchy and memorable enough for alt-rock radio, how exactly those unfurl is rarely predictable. The group freely switches between off-time, jazzy bits, stomping distorted choruses, and Beatlesesque lush harmonies, then back and forth again. One of the slickest iterations of these experiments to date is "Blood Pressure," the lead single off the band's most recent album, Odd Soul, which was released last October. With its VH1 video rotation and sing-along chorus, it may be the song that takes MuteMath to the next level.
