Shooting guns from one’s pointer fingers, making lazy karate chops and wriggling like a snake are the sort of dance moves that would look ridiculous if the person performing them doesn’t look slightly demented. But tall and lanky frontman Angus Andrew fits that bill, so this occasional silliness which punctuated his otherwise terrifying command of the microphone at the Rock and Roll Hotel Wednesday night just added to the atmosphere of insanity and darkness crafted by the (now) L.A.-based Liars.

Granted, it wasn’t hard to further this image given that they drew much of their set from this past year’s release, Sisterworld. Sisterworld takes the gloomy atmospherics from Drum’s Not Dead and fleshes it out with the fuller instrumentation that they brought to 2007’s eponymous release. The songs range from mosh-pit inducing tinny aggression (“Scarecrows On a Killer Slant”) to slow and creepy numbers that could potentially soundtrack a psychological horror movie (“Here Comes All the People”), and yet others that can go from gloomy and morose to loud and momentous within the course of the song (“Scissor.”)
