Commenter dbjack46 was asking about the pianist in A Little Incidental Music. Here is what I found out from the wiki.

Arcadi Volodos (ursprünglich russ. Аркадий Аркадьевич Володось/Arkadi Arkadjewitsch Wolodos, wiss. Transliteration Arkadij Arkad'evič Volodos'; * 24. Februar 1972 in Sankt Petersburg) ist ein russischer Pianist.

Volodos erhielt mit acht Jahren ersten Klavierunterricht und widmete sich dem Instrument erst mit fünfzehn Jahren intensiver, da er sich zuvor auf Gesang und Dirigieren konzentriert hatte.

Seine Lehrer waren Galina Jegiasarowa, Jacques Rouvier und Dmitri Baschkirow. 1997 gelang ihm der internationale Durchbruch mit einer von Horowitz' ehemaligem Produzenten Thomas Frost bei Sony veröffentlichten CD mit Klaviertranskriptionen, darunter einige von ihm selbst. Sein Debüt in der Carnegie Hall 1998 wurde aufgezeichnet und ist als CD erschienen.

The emergence of important new talent inevitably brings with it the thrill and exhilaration of discovery and promise. There was just that sense of excitement and curiosity on October 21, 1998, when the audience began filling Carnegie Hall for the New York recital debut of Arcadi Volodos. Over the last couple of years, the twenty-six-year-old pianist has been making his way as a quiet sensation. While rising from relative anonymity to conquer the major concert halls of Europe and garnering rhapsodic responses from audiences and critics alike, Volodos has, surprisingly, received relatively low-keyed publicity compared to the volume that greeted, say, Horowitz's arrival. By October 1998 New York concertgoers had had only two opportunities to savor Volodos' handiwork: performances of the Second Rachmaninoff Concerto with Seiji Ozawa and the Boston Symphony (December 1996) and Rachmaninoff's Third with Riccardo Chailly and the Concertgebouw Orchestra (February 1998). As a result, avid lovers of lapidarian pianism, who had discovered Volodos through his authentically brilliant first recording for Sony Classical (SK 62691), were eager to get a more inclusive "fix" on his musical and pianistic persona.

Mr. Volodos was born in Leningrad (now, of course, St. Petersburg) and, like some other fabled Russian musicians (Sergei Rachmaninoff and Sviatoslav Richter, among them), had not primarily aspired to be a virtuoso concert pianist. Years earlier, the young Artur Schnabel was told by his guru Leschetizky, "You are a musician, never a pianist." Volodos, of a different temperamental stripe than Schnabel, also proved himself - as evidence unfolded - to be a splendid musician, although stylistically more akin to two other alumni of Leschetizky's apparently endless studio, Ossip Gabrilowitsch and Benno Moiseiwitsch. In their esteemed company, Arcadi Volodos is a true lyric virtuoso - a keyboard poet who can touch and warm the heart, even when inspiring with astounding technical feats. I make no secret of being a nonworshiper in my response to pyrotechnical acrobatics, but even I am not averse to an occasional swig of "firewater" in moderation. Virtuosity in excelsis is essentially a social activity - and best enjoyed with fellow drinking (or listening) companions. Without further equivocation, let it be chronicled that Volodos is an authentic hero - an exemplar of the Russian virtuoso school at its best.
