<4.000000>Of Montreal, a product of the Athens, Ga., collective Elephant 6, creates esoteric disco music for eager dancers—and on the group’s new album, Aureate Gloom, it’s expanded on that sound. Don’t be surprised when ‘70s metal guitar commingles with dancefloor bass, as in catchy album opener “Bassem Sabry,” named for an Egyptian journalist who died last year. Recorded in the Texan desert just across the border from Ciudad Juarez, Aureate Gloom is, like most everything in of Montreal’s discography, full of song titles so specific as to be nearly inscrutable; help us out with “Chthonian Dirge For Uruk The Other,” will ya? This is band-as-wild-spectacle, and that carries over to the outfit’s live performances, which are rife with elaborate sets and fluorescent costumes. Of Montreal performs with Yonatan Gat at 8 p.m. at 9:30 Club, 815 V St. NW. $20. (202) 265-0930. 930.com.
