Tullis Rennie is a composer, electronic musician, improvising trombonist, and field recordist. He has appeared in collaboration through performance and recording with an array of artists including Claudia Molitor, John Butcher, Cath Roberts, Olie Brice, Kate Carr and many others. Tullis’s varied career to date has touched upon many different conceptual approaches, examining the impact of listening with jazz musicians Matthew Bourne and Graham South on vinyl-only release Muscle Memory ("...Rennie foregrounds the act of listening as an active component in the creation of musical experience” -– The Wire Magazine), and investigating the hidden process of performance preparation with Manchester-based Vonnegut Collective on 48 Hours (Moving Furniture Records). His recent studio work Fixed Freedoms, released on Matthew Herbert's Accidental Jnr label, is "a mutated set of electronic experiments that bends recognizable formulae (trance, dub techno, electro) into abstract landscapes" — Boomkat. He is co-founder of Walls On Walls with visual artist Laurie Nouchka, and a member of the Insectotròpics audio-visual collective, based in Barcelona.
