Though they share a name with a sunken, Atlantis-esque continent, the Buffalo punks that make up Lemuria didn’t take long to find themselves. Beginning with their self-titled 7-inch debut, guitarist Sheena Ozzella and drummer Alex Kerns (who share vocal duties) crafted a particularly self-assured brand of post-hardcore, a sound that only grew more refined on their 2011 effort, Pebble, with the added production touch of Jawbox’s J. Robbins. The band — which has included bassist Max Gregor since 2010 — spent parts of December and January holed up once again with Robbins in his studio in Baltimore, emerging now with “Brilliant Dancer,” a bipolar bit of melodic punk that manages to float some plinking piano chords over Ozzella’s and Kerns’ honeyed vocal takes and characteristically hearty guitar work.
