Late last year, the five-strong Primordial Undermind released Loss of Affect on the Strange Attractors label. The album’s a triumph of less-ism, not so much minimalism, with its Zen patterns and often terse vocabulary, but music far more select and simple than its various contributors’ involvement might suggest. Specifically, on tracks like the freely available “Breathe Deep” (MP3), the group explores the revived folk-as-art realm with a heady, deeply strummed, lithe romanticism. Fellow traveler Douglas Ferguson guests on “electronics” elsewhere on the album. This is quintessential less-ism: music that is less than the sum of its parts, and all the better for it.
