My son calls it “spooky alien music but in a good way.” Krautrock grooves underpin an ever evolving sound collage. Instruments, voices, and noises sometimes float by barely notices and sometimes shock you back into the groove. Concrete Islands uses the phrase “murmurations from unknown tongues” to describe the bands music, and that seems about as apt as any description we’re likely to conjure.
The title track emerges from primordial squigglings over an ever-reliably-chugging bassline and builds upon a repeated phrase dervishly swirling and repeating and building and repeating and building and swirling. The piece doesn’t so much resolve as exhaust itself in experimental ecstasy. ‘Tangled Hands’s fleeting fog swirls through the atmosphere punctuated by skronks and ambient waves.
The album’s centerpiece, the nearly 21-minute ‘Bubbling Pelt’ was recorded live at TUSK Festival 2020. The piece bubbles and swirls over minimal but hypnotic bass rumblings. Percussion skitters back and forth until becoming one with the ether. As the bass returns, wind instruments and electronic squiggles reveal themselves from the fog, forming a nice relaxed groove which gives home to all sorts of vocalizations.
Though heavy on krautrock repetition, this is not background music. Though it requires your attention, it grooves in unexpected ways.
Boulder Blues is out August 05th on Ramble Records and is highly recommended.
