Madison’s Null Device has grown more and more eclectic in methodical steps: Last year’s Excursions not only pulled together electronica, Middle Eastern and Indian music, industrial and pop, but also made sense out of the crossbreeds (for the most part). Just like most things within a mile of industrial music, it gets a bit maudlin at times, and the vocals aren’t as flexible as the music itself – though that shouldn’t keep anyone from admiring the aqueous electro-pop of “You’re Not That Charming” or “Twisting and Turning.”
