Too often, math rock gets caught up in its complexity without constructing enough openings to let in light. That's not the case with Montreal's Do Make Say Think. Its flowing, postrock soundscapes boast plenty of color and inviting warmth that blend ringing acoustic guitars with tasteful strings and inventive arrangements. Though prone to long-windedness, the band isn't as sparse, slow, tuneless or redundant as some of its more acclaimed instrumental peers. In fact, just three of the eight tracks on the recent You, You're a History in Rust tread far beyond five minutes, getting to the melodic point with elegance and alacrity.
