Hamelin has made recordings of a wide variety of composers with the Hyperion label. His recording of Leopold Godowsky's complete "Studies on Chopin's Études" won the 2000 Gramophone Magazine Instrumental Award. He is well known for his attention to lesser-known composers especially of the late nineteenth and early twentieth century (Max Reger, Leo Ornstein, Nikolai Roslavets, Georgy Catoire), and for performing works by the pianist-composers Sophie-Carmen Eckhardt-Gramatté, Leopold Godowsky, Charles-Valentin Alkan, Kaikhosru Sorabji, Nikolai Kapustin, Franz Liszt, Nikolai Medtner and Frederic Rzewski.
