Doom metal is a particularly cumbersome description of a genre, since there’s really nothing ominous or foreboding about the music. In Pallbearer’s case, it also falls way short of describing what the band actually does. The Little Rock-based foursome plays technical, solo-filled metal without getting noodly or devolving into endless jams, and there’s enough crunch and down-tuned minor chords to keep things spooky. Pallbearer, which is opening for Obituary at the Gothic, owes as much to progressive rock bands like Styx or Rush as it does to Black Sabbath and the Obsessed. The band’s three-album canon (and multiple ancillary EPs and singles) was created in a mere eight years, and it’s brilliant, diverse and deep.
