Errant Sounds brings together works by contributing members and friends of Errant Sound, a Berlin-based project space focusing on sound art and related practices. The 16 contributions represent a broad spectrum of positions with a particular focus on the materiality, spatiality, technicality and diverse cultural forms of sound. The pieces question the relationship between improvisation and composition, between performance and installation, between formal-aesthetic approaches and those that dissolve usual boundaries between subject and environment. The contributions by Roberta Busechian, Andrei Cucu, Nico Daleman, Georg Klein, Thom Kubli and Georg Werner combine sound principles of electronic and digital processes with social and media-political issues. Pieces by Jutta Ravenna and Gerriet Krishna Sharma negotiate how space unfolds and lends depth to our experience of time. Laura Mello, Jeremy Woodruff and Max Joy place sounds from field recordings of urban soundscapes and social processes in the foreground of their pieces and process them with compositional methods or let them speak for themselves. Mario Asef, Steffi Weismann and Janine Eisenächer question everyday objects for their haptic sonority. Alessandra Eramo, Zorka Wollny and the Psychedelic Choir as well as Gívan Belá, Golo Föllmer and Anne Wellmer work on the boundaries of voice and song.
