Another masterpiece of British jazz reissued on Universal's outstanding Impressed Re-pressed series, where it joins other long unavailable classics such as Amancio D'Silva's Integration , reviewed last month. Recorded in '69, Greek Variations & Other Aegean Exercises is irresistible on two counts. First, for its daringly conceived and brilliantly performed music, inspired by Greek folk songs and instrumental textures and deep enough to reveal all its treasures only after many repeated listenings. Second, for being recorded at the moment when the Don Rendell/Ian Carr Quintet, a major force in British straight-ahead jazz since '62, had broken up and Carr's equally influential jazz-rock band Nucleus was rising from the ashes.
This shoegaze supergroup (featuring members of Mogwai, Slowdive and Editors) turned heads with their debut of last year, proving to be rather more than the sum of their parts, yet they've surmounted expectations here by producing something if anything even more special. Whilst the title of this new work might suggest a more ornately arranged and overblown variant on the shimmering guitar overload of their earlier incarnation, 'Orchestral Variations' triumphs by stripping these songs back to their bare essence, arriving at an emotional resonance and wintry melancholia that is a wonder to behold.
This CD contains the first recording of the complete Chorale Variations by Daniel Magnus Gronau, a master from 17th century Danzig, “the finest musical soul ever to have graced the city of Danzig” as his pupils said after his death. He wrote a treatise on transposition, and the Chorale Variations form one of the most extensive compendiums of organ registrations of late Baroque organ music in Germany. Organist Matteo Venturini is a winner of no less than 8 prestigious organ competitions, and wrote a thesis on the organ music of Gronau. He plays on a magnificent Ghilardi Organ in the Church of San Rocco, Larciano. Booklet includes liner note and artist biography in Italian and English. All organ specifications are also included.
Mitsuko Uchida has been a committed exponent of Schoenberg's Piano Concerto for over a decade now. It is a work which remains controversial in its adaptation of the serial method to an almost Brahmsian harmonic palette, wedded to a formal approach that takes up the integrated design, and textural richness, of Schoenberg's pre-atonal works. Certainly in terms of the balance between soloist and orchestra, this recording clarifies the often capricious interplay to a degree previously unheard on disc (and most likely in the concert hall too).Interpretatively, it combines Pollini's dynamism, without the hectoring touch that creeps into the Adagio's climactic passages, and Brendel's lucidity, avoiding the deadpan feeling that pervades his final Giocoso.
While Sergey Rachmaninov is justly celebrated for his piano concertos and symphonies, his sets of variations shouldn't be overlooked, for they are among his most inventive and satisfying works. Russian pianist Danil Trifonov plays the Rhapsody on a Theme of Paganini, the Variations on a Theme of Chopin, and the Variations on a Theme of Corelli on this 2015 Deutsche Grammophon release, and he offers his own special tribute to the composer in his solo piano suite, Rachmaniana. For the Rhapsody, Trifonov is joined by Yannick Nézet-Séguin and the Philadelphia Orchestra, an ensemble that counts historic performances with Rachmaninov as part of its heritage, and plays with its characteristic lush sound and passionate expression…
