“We never can just settle on formula — that would make me insane,” Liars frontman Angus Andrew said about his band’s most recent album, last summer’s palindromic WIXIW. “We have to take risks and just fuck things up anew every time. It’s ingrained.” Since the new millennium, Liars has consistently been taking risks and fucking things up anew, on such records as 2001’s They Threw Us All in a Trench and Stuck a Monument on Top, 2004’s They Were Wrong, So We Drowned, and 2010’s Sisterworld, experimenting in multiple genres, from postpunk to dance to electronica, but always with unique twists. Singer-guitarist Andrew, guitarist and synth player Aaron Hemphill, and drummer Julian Gross should provide plenty of twists this weekend, when they play the Temple of Dendur at the Metropolitan Museum of Art on Saturday night, followed by a show Sunday night at (le) poisson rouge with Doldrums as part of the Wordless Music series; the concert was initially supposed to take place in the Brooklyn Masonic Temple, near the band’s sometime home base. As a bonus gift to their fans, Liars has just released a video of a new song, “I Saw You from the Lifeboat,” which contains a link to a free download of that tune as well as the new “Perfume Tear”; after the two New York shows, the group will head across the pond for concerts in Spain, Italy, France, England, Switzerland, and Israel.
