I'm a sucker for the Amazon $5 album sales i get in my inbox, so I just bought three items on that plan on impulse:

Shostakovich, Sonata For Viola and Piano Op.147, Quartet No.11 in F minor, Op.122. Igor Uyrash, viola, Alexei Ludevig, piano, New Philharmonia Quartet. Link

Carter: Symphony of Three Orchestras, Varese:Deserts, Equatorial, Hyperprism. Pierre Boulez, New York Philharmonic, Ensemble Intercontemporaine. Link.

Kronos Quartet, with Wu Man - Tan Dun: Ghost Opera. Link.

This features Wu Man on the pipa, to whom I was recently introduced in this amazing video posted by /u/OhHojotoho.

I also have two new ones from emusic.com:

Knussen: Symphonies Nos. 2 & 3; Trumpets, Cantata, Ophelia Dances, and Coursing. Oliver Knussen and Michael Tilson Thomas conducting.

I got this to begin to explore Knussen on the advice of /u/GoodGravyGraham. Boy, it's wonderful!

Tye: Consort Music - In nomine. The Spirit of Gambo|Freek Borstlap.
