The title refers to a Moroccan desert wind, but it was less a figurative association than merely the sound of the word that fascinated Johannes Boris Borowski. The lengthy one-movement work reveals the formal skills and the imagination of the composer born in 1979: A rhythmized melodic cell evolves into a construct with its very own structure, motivic-thematic work leads to two-dimensional sounds and eventually returns to the sparseness of the beginning. Chergui was commissioned by the state of Berlin and premiered at the festival Ultraschall in January 2013. The performance with the Ensemble Interface under the direction of Scott Voyles has been recorded and released on CD by Wergo. / Ensemble
