Musically Speaking: The Metric System Works

Canadian indie rock band Metric is on a roll right now, with a much-sought-after slot at next month’s Coachella festival in Indio, Calif., and its first DVD, “Live at the Metropolis,” in stores now. The band, which has opened for the Rolling Stones, consists of guitarist and producer James Shaw, vocalist and synthesizer player Emily Haines, bassist Josh Winstead and drummer Joules Scott-Key, is working on a follow-up album to 2005’s successful “Live It Out.”
