Sunless released their debut album, Urraca, in February, but their sludgy, dissonant sound has been steamrolling local music fans for a while now. The Minneapolis death-metal quartet’s thunderous live shows and filthy riffs have attracted the attention of metalheads everywhere, as evidenced by a successful U.S. tour with fellow locals Grogus. The pummeling drums of Ben Iburg form the unrelenting core to Sunless’ volatile, menacing sound, while guitarist/vocalist Lucas Scott brings a venomous twist. Sunless always manage to stay tight and focused, even when their sound borders on untethered dissonance — a testament to the group’s technical proficiency. Urraca stands as one of the best metal releases from the Twin Cities in recent memory, and Sunless find themselves leading a new generation of metal that’s shaking Minnesota — and the rest of the country — to its core.
