For all its impressive chart accomplishments of the past two years, Durham-based Merge Records has yet to win a Grammy Award (a milestone that another Triangle label, Haw River-based Yep Roc Records, achieved this year). But a Merge album did just win the Polaris Music Prize in Canada, given annually to the best Canadian full-length album as determined by an 11-judge panel. Caribou's 2007 Merge release "Andorra" is this year's winner, earning $20,000 (in Canadian dollars) for Caribou mastermind Dan Snaith.
