I've seen them in Toronto a few times and woken up the next morning to my face sore from smiling so much. All time top concert memory is seeing Kevin Drew and Feist sing Almost Crimes in 2010. I was right in front and was totally unprepared for Kevin Drew and Feist using the same mic for her parts. Song starts with Justin Peroff's drums and Andrew Whiteman's guitar parts, Kevin sings his first couple lines, steps aside, Feist steps forward and melts my face off.
Emily Haines even sang Anthems for a Seventeen Year Old Girl that night but Almost Crimes is etched into my brain forever.
Probably the band I've seen third most often after Tegan and Sara and Metric.
