In one of the most exciting releases of the year, young Russian virtuoso Daniil Trifonov is accompanied by his mentor Valery Gergiev on a new recording from the Mariinsky label featuring Tchaikovsky's powerful Piano Concerto No.1 and a selection of recital pieces (p.20). Trifonov, winner of the 2011 Tchaikovsky Competition, was hailed by the New York Times as having "scintillating technique and a virtuosic flair." Key titles from harmonia mundi include an album of rarely-heard choral works by Samuel Barber with the American ensemble Conspirare (p.11), the second volume in Isabelle Faust's traversal of Bach's solo Sonatas and Partitas (p,9) and new recordings of Schubert quartets and Beethoven sonatas by the Cuarteto Casals and Javier Perianes. Hyperion's three priorities for September include a recital of French piano music by Stephen Hough (p.13), a fourth volume in the label's series of the complete songs of Brahms (p.17) with baritone Robert Holl and a new addition to the Romantic Violin Concerto series featuring violinist Anthony Marwood playing works by Schumann (p.15). Conductor Iván Fischer and his Budapest Festival Orchestra return to the works of Gustav Mahler with a new multi-channel recording of the Symphony No.1 for Channel Classics (p.5). Music of the great Austrian composer is also the featured in the latest release from Onyx Classics. The acclaimed baritone Wolfgang Holzmair performs songs from Mahler's Des Knaben Wunderhorn accompanied by pianist Charles Spencer (p.22). In non-classical releases, the latest offering in APO's series of SACD remasterings of jazz classics presents Dave Brubeck's Time Out, which includes the all-time favorite "Take Five."
