“Darkly danceable” is how Pitchfork described Swedish hard rock quartet Graveyard. Joakim Nilsson, Rikard Edlund, Axel Sjöberg and Truls Mörck formed the band in ‘06, blending folk metal with blues rock. The result was a Myspace sensation, earning the band a Rolling Stone feature. The band’s most recent album, Lights Out, was released in the U.S. this past November. Graveyard plays The Orange Peel on Tuesday, Jan. 29, with The Shrine. 8 p.m., $14 in advance or $16 day of show.
