Patrick Crommelynck was born in Brussels in 1942, Taeko Kuwata in Tokyo in 1945. Patrick studied with Stefan Askenase at the Brussels Conservatory, with Victor Merzhanov at the Moscow Conservatory, and with Dieter Weber in Vienna, where he met Taeko Kuwata, who was another of Weber's students. They married and formed their duo in 1974. They came to attention with their two-piano version of Brahms's 4th Symphony. They achieved considerable praise and recognition and were considered one of the world's leading piano duos. They toured widely and a number of composers wrote works for them. These included André Tchaikowsky's Invention 5b, dedicated to Patrick, and another André Tchaikowsky composition Tango and then Mazurka were arranged for the duo.
