Brilliant Colors formed in 2007, but the all-female trio sounds like it could've been birthed in 1977 or 1987. On the threesome's debut LP, Introducing (released last year on local label Slumberland), the band re-creates the speedy tempos, buzzsaw guitars, and yelping vocals of such earlier grrl-fronted postpunk acts as Kleenex and the Shop Assistants. Such music seems like it'd be easy to make — turn the volume up to 11, set a steady beat, yell — but only when someone like Brilliant Colors does it really well does it become clear how difficult it is. There's a necessary tunefulness buried beneath the fuzz and clamor of Introducing, as well as a no-bullshit attitude that's highly engaging. Or, as the British say, "brilliant."
