Canadian quartet Metric return to Chicago on Nov. 24 to play the UIC Pavilion in support of Paramore. Still enjoying the success of 2012’s Synthetica, which was nominated for a Polaris Prize, the indie-pop band recently released a companion album on iTunes. Synthetica Reflections offers an atmospheric take on the tracks performed entirely on analog synthesizers. Accompanying the album is a Synthetica app for iTunes, which allows users to remix and filter Metric songs. Chicagoist caught up with lead vocalist Emily Haines somewhere between New York and Boston to reflect on technology’s effect on the music industry and how some things never change.
