French cellist Maurice Gendron (1920-1990). His origins were poor and he hailed from Nice. At the age of three he took up music, starting with the violin, but his mother then gave him a quarter-sized cello and he was drawn to it immediately. The rest is history. At ten he was introduced to Emanuel Feuermann, and at twelve he was admitted to the Nice Conservatory, winning first prize at fourteen. Then it was on to the Paris Conservatoire to study with Gérard Hekking. Whilst there he supported himself by selling newspapers. When war broke out he was declared unfit for active service due to malnourishment, so he became a member of the resistance.

Grumiaux’s elevated intellectual profile is put to exalted use in the Debussy Sonata. He has a quicksilver response to the music’s twists and turns and an alertness to the necessary momentum in the first movement. He is thus forward moving but flexible with a fast vibrato and multi variegated tonal response at once apposite and unostentatious. Listen at 2.15 to about as extravagant a portamento as he ever made on disc. If you want to hear fluent and incisive duo playing listen to Grumiaux and Hajdu in the Intermède where understanding of motivic details and larger structure reigns supreme.
