David Toop has been developing a practice that crosses boundaries of sound, listening, music and materials since 1970. This encompasses improvised music performance, writing, electronic sound, field recording, exhibition curating, sound art installations and opera. In the past he has collaborated with a wide array of musicians, including Ryuichi Sakamoto, Akio Suzuki, Lawrence English, John Butcher, Thurston Moore, Fred Firth and many others. He has written eight acclaimed books, released fourteen albums and curated a number of exhibitions.

Avsluta (Lucie Stepankova) is a sound artist, electro-acoustic composer and performer, free-improviser and lecturer of improvisation and performative practice at London College of Communication. Avsluta works with objects and natural materials, field recordings, electronics and digital processing. The general aim of her practice is to encourage audiences to engage in listening as an active-creative practice, reconnect with and embody emotions, and discover new approaches towards solidarity as understood within the framework of deep ecology.
