PIERRE BOULEZ — Boulez Conducts Mahler : Complete Recordings (2013) 14CD BOX-SET | FLAC (tracks), lossless

Between 1994 and 2011, Pierre Boulez recorded the symphonies and songs of Gustav Mahler for Deutsche Grammophon, and for many listeners these recordings are high points in his catalog, while others regard them as idiosyncratic recordings for specialists. The basis of both views stems from Boulez's meticulous conducting and exacting performance standards, which produce music of extreme lucidity and precision, yet which can also seem overly cerebral and dispassionate. Boulez's approach to Mahler may seem clinical, and this is a reasonable assessment of the way he treats details, textures, timbres, dynamics, and rhythms as indicated in the score, clearly and cleanly, without adding personal touches or interpreting the music through Mahler's biography or his own mythology. In short, Boulez goes back to what Mahler actually wrote and avoids the distortions of post-Romantic tradition and the exaggerated choices of superstar conductors. If this means Boulez is out of the mainstream of, say, Leonard Bernstein, Georg Solti, or Herbert von Karajan, his zeal for exactitude is often matched by his contemporaries, Claudio Abbado, Michael Tilson Thomas, Benjamin Zander, Jonathan Nott, and Jaap van Zweden. The sound of these recordings varies slightly from disc to disc, but Deutsche Grammophon's high standards are consistently met. Blair Sanderson

IGOR STRAVINSKY : Le Sacre du Printemps · Pétrouchka (Chicago Symphony Orchestra · Sir Georg Solti) (1995) APE (image+.cue), lossless

This immensely powerful and incandescent performance by The Rite of Spring (recorded in excellent stereo in 1974) is definitely one of Solti's great performances with the Chicago Symphony Orchestra (and even better than the one recorded live in the 90s with the Concertgebouw). The director draws a relentless forward momentum at a fast-paced pace and, at the same time, vividly highlights all the details of the score. It is a direct performance where music takes an incredible life with vigor and primeval force, thanks to the excellence of the strings, winds and metal sections.
Some of the above temperament can be applied to the original version (1911) of the Petrouchka ballet, recorded in the mid-1990s by the same performers, although now savage primitivism is aptly tempered by the greater refinement of a more dancing-style.
In any case, a sensational disc with a shocking sound that would have deserved editorial content equal to the performances (without informative notes of the works or exact dates of recording). Amazon    Tracklist & Credits :
