Trio Transmitter plays current music, for and about the present day. Through a large number of preparations and expanded playing techniques, the three musicians coax highly differentiated and very personal sounds from their instruments. The most varied objects, such as record players, megaphones and additional recordings, enrich the sonic possibilities, becoming integral parts of the compositions. An important factor in this is the collaboration with the composers, who are engaged in constant exchange with the ensemble even in the compositional process. Since its founding in 2012, the Trio Transmitter has commissioned and premiered diverse compositions, receiving a furtherance prize of the Initiative New Music Berlin in 2015. Camera Obscura features compositions by Florian Bergmann (with texts by Ronald D. Laing), Markus Wettstein, Nuria Núñez Hierro, Hanna Hartman and Benedikt Bindewald. Trio Transmitter are: Florian Bergmann - bass clarinet; Benedikt Bindewald - violin and viola; Alba Gentili-Tedeschi - piano. Additional personnel on Camera Obscura: Jonathan Sheratte, Rilli Willow - voices on "Knots I"; Sarah Saviet, Benoit Pitre - voices on "Knots I" & "Knots II"; Georg Bochow - countertenor on "Knots III".
