Chicago’s A Lull is nearly impossible to describe without qualifiers. Equal parts mystical and primal, the music crafted by these five multi-instrumentalists gathers the recognizable traits of a half dozen indie micro-genres, tosses out all but the stem cells, then adds the calculated, percussive verve of a half dozen rhythm sections on top of beautifully crafted songwriting to result in a sound that is as unique as it is memorable. A Lull blurs the lines between the synthesized and organic.
