Mr. Valkov has appeared frequently as a recitalist in the U.S., China, Japan, England, Norway, Germany, Italy, Greece, Bulgaria, and Macedonia. A Japanese tour took him to Tokyo, Toyama, Yokohama, and Okinawa. He has performed with most of the major orchestras in his native Bulgaria, and at most of the country’s important music festivals. He debuted with the Sofia Philharmonic Orchestra, and performed Dimitar Nenov’s Grande Piano Concerto with New Symphony Orchestra under Rossen Milanov, becoming the fifth pianist to perform the concerto, and the only one to do so in its entirety. Mr. Valkov has made a number of recordings for the Bulgarian National Radio archive and has recorded for Bulgarian National Television and Macedonian Radio and Television.

Mr. Valkov’s concerts reflect a vast interest in chamber music as well as lesser-known piano repertoire. He frequently performs with Bulgarian cellist Lachezar Kostov.

In 2009, the Kostov-Valkov Duo gave its Carnegie Hall debut in Zankel Hall, and in 2011 won the Liszt-Garisson International Competition, where they were also awarded the Liszt Prize and special prizes in the collaborative artists category. In 2008, they recorded the entire opus for cello and piano by Nikolay Roslavets, released by Naxos in 2011. Their second CD, Transcriptions and Paraphrases, was released in 2015 and featured their own arrangements of Liszt’s Hungarian Rhapsodies Nos. 1 and 2, and the Evocation à la Chapelle Sixtine.

As a soloist, some of Mr. Valkov’s recent projects include Beethoven’s Hammerklavier sonata and Busoni’s Fantasia Contrappuntistica. He has presented a program highlighting composers of the 1600’s, including Froberger, Couperin, Frescobaldi, and Buxtehude, and selections from The Fitzwilliam Virginal Book. His first solo CD was a Naxos release of the complete piano music of Dimitar Nenov. Viktor Valkov is an Assistant Professor of Piano at the University of Utah.
