Acrid Lactations (Susan Fitzpatrick and Stuart Arnot) “fold musique concrète techniques and sound poetry into broken jazz and electronics in a putatively, primitivist improvisational practice”. For Tectonics they will be performing a musico-spatial improvisation for assorted instruments, voices and miscellany. Mats Gustafsson’s PLUGS (2000) for mixed ensemble and conductor is presented in a new extended version and is a study of the expected and unexpected and a celebration of the capabilities of listening, thinking and acting freely. It is dedicated to Dror Feiler. With Danielle Price (tuba), Sue McKenzie (soprano sax) and Laura Macdonald (alto sax).
