Man, this thread makes me feel like a stranger in a strange land. I've not heard of the majority of artists, much less the releases you folks are talking about. I do look forward to the Joanna Newsom adiZero mentioned. Indeed, after her last one, Y's, I don't know what to expect, but Milk Eye'd Mender is certainly a favorite disc.
The only release I've purchased thus far from 2010 has been Patty Griffin's, "Downtown Church". Patty can do no wrong by me. This one took a bit of getting used to but now I really have warmed up to it. I've purchased plenty of other music in these first two months of this year, but none of it released in 2010. Good idea for a thread.
