The award-winning Kostov-Valkov Duo (Lachezar Kostov on piano and Viktor Valkov on cello) has performed in world-class music halls around the world, including Carnegie Hall and the Gewandhaus of Leipzig. So it would be reasonable that the pair would have a somewhat casual approach to performing in a gallery at the Museum of Fine Arts, Houston. Not so, Kostov tells us via email. โ€œThe Houston Friends of Chamber Music had the fantastic idea to pair current exhibitions at the MFAH with performances of works directly connected to the art, and they had secured a great performance space, as well as a top-notch piano in the big gallery at the MFAHโ€ฆwe knew that something remarkable would come out of it.โ€

The two will be joined by violinist Oleg Sulyga for A Musical Homage to Sargent by Trio SLAVA. (The three have worked together under the name before.) The program includes works by John Singer Sargentโ€™s contemporaries Frank Bridge, Edward Elgar and Gaspar Cassado. โ€œWe open the program with Phantasie for Piano Trio by Frank Bridge โ€” a lush, romantic one-movement work that [transports] the listeners toโ€ฆLondon [at the turn of the 20th century],โ€ Kostov says. Oleg Sulyga performs short works by Elgar and Shchedrin. The Kostov-Valkov Duo performs โ€œRossini Variationsโ€ for cello and piano, by Czech composer Bohuslav Martinu. (Kostov calls the work โ€œone of the milestones of the 20th-century repertoire for cello and piano.) Piano Trio in C Major by Catalan cellist and composer Gaspar Cassado closes the program.
