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, Plus–Minus 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. 

Plus–Minus 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 Series at L’Auditori in Barcelona, Klang Festival in Copenhagen, Fundaci√≥n BBVA in Bilbao, Huddersfield Contemporary Music Festival, MaerzMusik, Spor Festival in Aarhus, Transit Festival in Leuven, and Ultima in Oslo. Plus Minus 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, Plus Minus has recently worked with composers such as Peter Ablinger, Laurence Crane, Bernhard Lang, Cassandra Miller, James Saunders, Alexander Schubert, and Jennifer Walshe.
