September 13. For sheer Dungeons and Dragons bombast, the Rockland County/Hudson Valley-conceived Coheed and Cambria tops the misty mountain. The current lineup of grand wizard Claudio Sanchez (vocals, guitar), Travis Stever (guitar), Josh Eppard (drums), and Zach Cooper (bass) sprang forth in 2001 from the remains of the trio Shabutie, and has since conquered the contemporary prog-metal universe with its five high-concept “Armory Wars” sci-fi-themed albums, novels, and comic books (a Mark Wahlberg-produced fantasy film is due out soon). Local outfit 3, featuring Josh’s brother, Joey Eppard, opens this show at the Bardavon. (Steve Earle strums September 30.) 8pm. $28. Poughkeepsie. (845) 473-2072; Bardavon.org.
