Was compelled by social arrangements to listen to Santigold's 99c a few times recently, and really enjoyed it. Would never have chosen to listen to it, because from the name I would never have guessed she'd sound anything like what she does.

I've now gone back and listened to her first 2 albums and realised not only that I know (and enjoy) a couple of songs from each, but that on the whole they are also very good albums.

Which established artists have you "discovered" in the last 12 months or so through a recently released album?
