The world premiere recording of Maurice Vieux's Études for solo viola is presented in a double album, masterfully interpreted and performed by Marco Misciagna, who for the first time in history records and performs in a highly evocative recital performing the 20 Études for solo viola (1927), the 10 Études sur des traits d'orchestre for solo viola (1928), the 10 Études sur les intervalles for solo viola (1931) and the 10 Études Nouvelles for solo viola (1956). This is the first world recording of these Études (50 in total) composed by Maurice Vieux, which aims to highlight a hitherto little or not at all known aspect of what can be called, without any doubt, a "pillar" of modern violist art. A titanic undertaking, which adds a great piece to the history of this instrument, hitherto unexplored. With dedication and passion, Misciagna has put himself at the service to create a work of great musical depth, demonstrating great artistic sensitivity and exceptional technique.
