On her six-song debut, Yara Jakymiw proves herself a capable singer but restrains her voice, never treating it as more than just another instrument. It's with this spirit of moderation that Plant Life thrives, keyboards, sampled instruments and blurts of electronic sound selected and arranged just so, the percussion soft but persistent, like a baby's heartbeat. Some songs begin with IDM's familiar frost, gradually boiling to the payoff point of bright, symphonic melodies. It's like a hybrid of the Postal Service and something you'd hear at a Patti Schmidt house party. Yara blossoms at her CD release party at Clinton's Friday (September 10).
