This album is Mastered for iTunes. With Synthetica, Toronto-bred electro-rockers Metric continue to blend sharp lyrics, memorable melodies, and formidable beats with modern instrumentations. “Speed the Collapse” presents an unfolding drama driven by nervous-sounding drumming; “The Wanderlust” perfectly contrasts Emily Haines’ sweet singing with the legendarily unflappable delivery of guest duet partner Lou Reed. The horns toward the end of the title track, in turn, warmly complement its raw guitar power.
