On their debut Navona Records release Transcriptions and Paraphrases for Cello and Piano, the Kostov-Valkov Duo – cellist Lachezar Kostov and pianist Viktor Valkov – present a powerful and invigorating program, showcasing their virtuosity through performances of works by Franz Liszt, Buxton Orr, Bohuslav Martinů, and Mario Castelnuovo-Tedesco. Exemplifying the Duo’s ground-breaking, limit-pushing and virtuosic arrangements are the three works by Franz Liszt, while the Orr, Martinů, and Castelnuovo-Tedesco pieces paraphrase and reference earlier works by Bizet and Rossini.
