Metric (myspace, last fm) is a rather interesting band, fronted by Emily Haines (also worth investigating as a solo artist in her own right: here's her last fm page).
Today's song, then, is Metric's Grow Up and Blow Away – which you may download (quite legitimately, it seems, here, or just stream from last fm) ... There is something rather French-sounding about this, isn't there? Think Air. The way in which it flits rather whimsically between major and minor keys, lifting you back up just as you think you're about to sink into melancholia. I enjoy the resultant overall emotional ambiguity.
... And it's well-produced. There's a sort of matt-laminated quality to Metric's sound. Like a nicely-printed flyer for a very high-end restaurant. Smooth, refined – but not glossy.
Best … chord-change?
Happens at 0.41 - takes the progression one step further than you expect. Makes the song.
The second half is a little more bland than the first, and the middle-eight is far less striking than other parts of the song – a bit safe.
