In a matter of minutes, Metric singer Emily Haines and guitarist James Shaw went from rocking in front of thousands of fans on the main stage of the Sasquatch Music Festival to hiking through a rumored thicket of rattlesnakes overlooking the Columbia River. The duo gamely made the trek for an acoustic performance of "Synthetica," the title track from Metric's new record. Stripped of an electric guitar and moody reverb, Haines and Shaw performed a version of the song pretty enough to challenge the sweeping sunset behind them. There couldn't have been a more appropriate backdrop for Haines' refrain, "Hey, I'm not synthetica."
