About the Program

During the 2019-2020 and 2020-2021 seasons the award-winning Kostov-Valkov Duo will be presenting Ludwig van Beethoven’s 5 Sonatas for Piano and Violoncello. Written in three distinct styles, the five sonatas are considered some of Beethoven’s finest in his chamber music output. Unlike the String Quartets and the Violin Sonatas, the Cello Sonatas can be performed in one evening. They are written in the span of 25 years and are quite unorthodox in their formal structure and instrumental characteristics. In the two early Sonatas op.5, the piano is the main protagonist, while the cello is taking a more supporting role. The later works - the A major sonata op. 69, and the two sonatas op. 102 are true duet pieces, in which both instruments play equal roles. 

Kostov-Valkov Duo’s performance will not follow the chronological order of the compositions, but rather juxtapose an early sonata with a later one, and ending the concert with the joyous Sonata in A major op. 69. There will be one intermission and one short pause before the last work. Total timing of the concert with two pauses is 2 hours and 25 minutes.

About the Artists

Cellist Lachezar Kostov and pianist Viktor Valkov have performed together for more than 15 years and have appeared at concert venues in the USA, Germany, Italy, and Bulgaria. In 2002 they were named winners of the “Grand Prix of the Music and Earth Competition” in Sofia, Bulgaria. After their early success the Duo performed a series of thematic concerts devoted to the music of Hungary, France, Germany, and Russia. Prior to establishing themselves in the USA Kostov and Valkov appeared in several European festivals, such as “Russian Music Days” in Dortmund, Germany.

The Duo’s first major performance in New York City was sponsored by the “Bulgarian Treasures” foundation and took place in Weill Recital Hall in 2008. Following their critically acclaimed debut at New York’s Zankel Hall at Carnegie Hall in 2009, the Duo has received high accolades for their inspired and unique performances. Critic Harris Goldsmith described them as “prodigiously skilled protagonists” and praised their “formidable virtuosity”. Devoted to rediscovering rarely performed works from the cello and piano repertoire, they perform compositions by Dmitri Kabalevsky, Camille Saint-Saens and Nikolay Roslavets, as well as many arrangements and transcriptions from the violin, viola, and piano repertoire. Some of the most successful arrangements performed by the Kostov-Valkov duo are Robert Schumann’s Violin Sonata in A minor, the Hungarian Dance No.5 by Brahms, Roslavets’ Viola Sonata, and the famous Hungarian Rhapsody No.2 by Franz Liszt. In 2010 Mr. Kostov and Mr. Valkov toured several German cities including Hasselburg, Waldorf, and Bad Saeckingen, performing to sold-out halls in celebration of the 200th birth anniversaries of Chopin and Schumann.

In October 2011 the duo entered the Fifth Liszt-Garrison International Piano and Duo Competition of the American Liszt Society at Baltimore-Washington, USA. The Kostov-Valkov duo was unanimously awarded the First Prize, as well as Best Interpretation Awards for the Performance of a Work by an American composer for John Corigliano’s “Phantasmagoria”, and for the Performance of a Work by Franz Liszt for their own arrangement of the composer’s “Hungarian Rhapsody No. 2”.  In addition to several concert engagements, the Lachezar Kostov & Viktor Valkov duo received the event’s special 2011 FRANZ LISZT AWARD for “Exceptional Performance on the Franz Liszt Bicentennial Year Celebration”.

In 2013 the Kostov-Valkov Duo made appearances in several US states, including Maryland, Washington, and Texas. A Japanese tour in 2014 took them to Tokyo, Kanaya, and Okayama.

The Kostov-Valkov Duo have so far released two recordings. The first one, published by NAXOS in 2010, received favorable reviews by the American Record Guide, Strad Magazine, and others, and  features the complete music for cello and piano of Nikolay Roslavets. Their second recording came out of Navona Records in 2015, and includes their own transcriptions virtuosic piano pieces by Franz Liszt.

In Germany the duo is represented by the Pro-Piano Management.
