Plus-Minus Ensemble is a London based ensemble 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. As of 2019 Plus-Minus has adopted a more collective model, with Mark Knoop and Vicky Wright stepping forward to join Matthew as co-directors.
+- has performed in London at Kammer Klang, Cafe Oto, BBC Radio 3 Open Ear, Cut and Splice, City University Concerts, and at Borealis (Bergen), Sampler Sèries (Barcelona), Klang Festival (Copenhagen), Fundación BBVA Bilbao, Huddersfield Contemporary Music Festival, MaerzMusik (Berlin), Spor Festival (Aarhus), Transit Festival (Leuven) and Ultima Festival (Oslo). In 2019/20, +- will play at Warsaw Autumn and MIRY Concertzaal in Ghent.
+- has an ongoing relationship with Bath Spa University and the Guildhall School of Music and in September 2019 will take on a three-year position as Ensemble in Residence at the Reid School of Music (University of Edinburgh). The group has also given workshops and concerts at Stanford University, Durham University, Huddersfield University, University of Southampton and City, University of London.
