2010 was all about classical for me. Lots of great rediscoveries for me, so nothing really new. Lots of Everest, Living Stereos, Mercury, Heifetz and Oistrakh.
Picked up quite a bit of it on vinyl too, which I always over looked but finding the right stuff just blows my mind how music so delicate can sound so good with what is basically a sharp rock dragging over a piece of plastic
I was disappointed with Arcade Fires new album, which I was hoping to love. The National High Violet was very good, but didn't grab me like their others. The new Deerhunter was great, but grew tired of quickly. There is probably more, but those 3 stand out in my head which is clogged up atm.
