Saturday 9/22 Metric, Tower Theatre, $28

The making of Metric’s fifth album, “Synthetica,” was accompanied by the making of a documentary about the band, and although the album was released in June, the documentary is still being rolled out to the public in pieces on Metric’s YouTube channel. In the words of lead singer Emily Haines, “Synthetica” is “about forcing yourself to confront what you see in the mirror when you finally stand still long enough to catch a reflection.”

Sunday 9/23 Catnaps, The Fire, $8

Catnaps (formerly known as When I was 12) are a local outfit who play, in their own words, “nightmare pop.” It’s well-crafted, fuzzy twee with lyrics both sweet and sharp, and if you appreciate indie pop, it’s pretty much impossible not to fall in love with it. Their latest EP, “Boys Drool,” came out in February 2011, but according to the group’s Facebook page, they’re hard at work on a new EP.
