With Françoise Kubler (soprano), he is the founder of the ensemble "Accroche Note", research and creative formation in contemporary music.
Born in Strasbourg, Angster's mastery of the different clarinets (soprano, bass clarinet[1] and metal doublebass) allows him to be the dedicatee of works by contemporary composers (Brian Ferneyhough,[2] Ansioso quasi con gioia (2015) by Stefano Gervasoni,[3] La mesure des choses I.
La mesure de l'air (1992) by Joël-François Durand,[4]) as well as their interpreter (Aleph (1985) by Philippe Manoury, Dikha by Christophe Bertrand, By the Way by Pascal Dusapin, Assonance III (1989) by Michael Jarrell).
In 1981, he created in Strasbourg with Françoise Kubler the Accroche Note ensemble[5][6] offering programmes combining music from yesterday and today; this ensemble is supported in particular by the Ministry of Culture and the City of Strasbourg.
He is soloist in various formations ranging from the Orchestre philharmonique de Radio France,[7] the Orchestre philharmonique de Strasbourg to ensembles of contemporary music in Europe (Nieuw Ensemble d'Amsterdam.
