Following a string of cassette-only releases, Northern California duo Some Ember released its eponymous debut album last month. On it, punishing drum machines underpin percolating synthesizers and the alternately woeful and menacing vocals of Dylan Travis and Nina Chase. For contemporary acts channeling industrial techno and EBM, tone is integral. Some Ember appreciates that production is more than form — it’s practically musical content. Percussive elements are honed to trenchant strikes and gauzy electronic textures are carefully wrapped in order to fully immerse listeners. Every sound is impeccably balanced in the mix. Some Ember also took the vinyl format into consideration. The A-side is assaultive and fierce; the B-side flirts with ambient house and synth-pop balladry. Production is so crucial to Some Ember that imagining the duo cast adrift on stage without the tools of a home studio is worrisome, but the group’s strength on record warrants investigating its live show at Night Light (311 Broadway, Oakland) nonetheless.
