Plus-Minus Ensemble is a London based collective committed to commissioning new work and placing it alongside recent and landmark modern repertoire. Formed in 2003 by Joanna Bailie and Matthew Shlomowitz, +- is distinguished by its interest in performative, electroacoustic and conceptual pieces, and experimental open works such as Stockhausen‘s 1963 classic, from which the group takes its name.

+- has regularly performed in London at Kammer Klang (Cafe Oto) and City University; has been broadcast on BBC Radio 3 and Deutschlandfunk Kultur; and has played at the Borealis Festival Bergen, Cut and Splice, the Sampler Sèries at l'Auditori in Barcelona, Klang Festival Copenhagen, Fundación BBVA Bilbao, Huddersfield Contemporary Music Festival, MaerzMusik, Spor Festival in Aarhus, Transit Festival Leuven and Ultima Festival Oslo.

+- also works with student composers and has given workshops and concerts at Bath Spa University, City University London, Durham University, Guildhall School of Music, Huddersfield University, Stanford University and the University of Southampton.

In addition to performing works by Bailie and Shlomowitz, +- has recently worked with composers such as Peter Ablinger, Laurence Crane, Bernhard Lang, Cassandra Miller, James Saunders, Alex Schubert and Jennifer Walshe.
