Well, I'm about 6 months late, and this list isn't even mine! Courtesy of ionarts, they list their 10 best New Releases, as well as the 10 best Reissues. I'm pleased to report that the Baroque era won first place in both categories - with Tharaud's Bach Recital picking up best new recording, and the "Scarlatti Cube" of 34 CD's and 555 Sonatas awarded best reissue. Now, that's one I'm going to have to save up for.
There's a miscellany of Barenboim, and Franck, and Verdi, and the Maxwell-Davies Naxos Quartets is a surprise selection. I'm not the biggest fan of Uchida or the Takacs Quartet, but they get double mentions. Full marks to the Pollini Schumann though, good taste.
