HRVRD Before they dropped the vowels in their name to avoid litigation with a certain hallowed educational institution, HRVRD was Harvard, a post-hardcore, neo-prog crew frequently compared to propulsive post-emo rockers Circa Survive. An emo hangover still hovers in HRVRD’s busy drumming, and prog (“neo” or otherwise) still echoes in coruscating guitar work that recalls Larks’ Tongues in Aspic-era King Crimson. Still, HRVRD’s shorter, sharper name signals a tightening and maturation of the band’s intricate sound. Comparisons to Circa Survive still surface in HRVRD frontman Jesse Clasen’s pure and ethereal vocals, but Clasen seems to hew closer to Tim Booth of ’90s Brit alt-rockers James. Indeed, HRVRD’s swooning melodies and swirling atmospherics suggest an update on Booth and the Bad Angel, the James frontman’s quirky and neglected collaboration with Twin Peaks composer Angelo Badalamenti. Even that cult LP is just one of many sonic touchstones for this band. Complex, soulful and soaring, with a tinge of darkness, HRVRD charts its own disquieting course. Performing at the 4th Annual Philip & Terrence Birthday Celebration featuring Junior Astronomers, Yardwork, Oddczar, It Looks Sad, That’s Why I Said It’s You. Free. Oct. 26, 8 p.m. Tremont Music Hall, 400 W. Tremont Ave. 704-343-9494.
