Armand Jakobsson’s wacky DJ alias may suggest a winking irony, but the Swedish electronic musician’s radiant deep house is really as heartfelt as it gets, pairing moody basslines with suggestive tape hiss and melancholy melodies. Early cuts like 2017’s muted “Ruff Hysteria” reflect the lo-fi aesthetics of their period; “I Hope I Sleep Tonight” wraps a swooning vocal hook in spare but sprightly drum machines. Seinfeld’s music has gotten more emotive ever since, stoking starry-eyed bliss on both the disco-kissed “U Already Know” and the jungle-driven “Electrician.”
