Joël-françois Durand: Geister - This double album with compositions from the last two decades offers an insight into the diverse musical soundscape of Joël-François Durand. - This double album with compositions from the last two decades offers an insight into the diverse musical soundscape of Joël-François Durand. From Mirror Land (2005) to Geister, schwebende Geister... (2020), Durand's work shows a unique development characterised by his use of microtonality. The poetic dialogues of the Fernando Pessoa-inspired Quatuor à cordes No. 2: Cantar de Amigo (2020) and Durand's ongoing exploration of microtonal spaces in La descente de l'ange (2022) reveal a dynamic and transformative universe of this extraordinary composer.
