In terms of linear time, everything current is post-punk. The label, however, is still tossed around to describe bands that capture the artier, more expansive, and psychedelic sound that grew out of its predecessor. Indiana’s TV Ghost actually sounds like it could have existed in 1981, capturing not just the general musical approach but also its strange tonality, simultaneously tense and atmospheric. The group’s earlier records provide scuzzier takes on the genre, but Disconnect, released in September, will send geezers back to the early years of Echo and the Bunnymen, nailing in particular the haunted ambiance of 1981’s Heaven Up Here. While it’s hard to say if TV Ghost has a classic like Echo’s Ocean Rain in its future, Disconnect provides a welcome flashback to the post-punk past. TV Ghost performs with Holograms at 8:30 p.m. at DC9, 1940 9th St. NW. $10–$12. (202) 483-5000. dcnine.com.
