Preceded by a series of singles over the last couple years, Cadets is the full-length debut from Los Angeles four-piece Spirit Mother, and it packs expanse into deceptively efficient songs, seeming to loll this way and that even as it keeps an underlying forward push. The near-shoegaze vocals do a lot of the work in affecting a mellow-psych vibe, but there’s weight to Spirit Mother‘s “Ether” as well, violin, woven vocal layers, and periodic tempo kicks making songs standout from each other even as “Go Getter” keeps an experimentalist feel and “Premonitions” aces its cosmic-garage driver’s test with absolutely perfect pacing. The ultra-spacey “Shape Shifter I” and more boogie-fied “Shape Shifter II” are clear focal points, but Cadets as a whole is a marked accomplishment, particularly for a first LP, and in style, substance and atmosphere, it brings together rich textures with a laissez-faire spontaneity. The closing instrumental “Bajorek” is only one example among the 10 included tracks of Spirit Mother‘s potential, which is writ large throughout.
