Percy Grainger, The Complete 78-RPM Solo Recordings 1908-1945 (Appian, five CDs). The composer of “Country Gardens” and “Molly on the Shore” was also one of the greatest pianists of the twentieth century, a marvelously idiosyncratic virtuoso whose style ranged from tender lyricism to explosive extroversion. Most of his 78s have been unavailable in any format since their original release. This much-needed box set solves that problem–and does it right. Ward Marston’s digital transfers of such classic Grainger recordings as Chopin’s B Minor Sonata, Schumann’s Symphonic Etudes, and Grieg’s “Wedding Day at Troldhaugen” are crystal-clear and scratch-free. The liner notes are by Grainger biographer John Bird. I doubt there’ll be a more important classical reissue in 2011 (TT).
