At the South Bank Centre’s New Music Biennial weekend (4-6 July), a mini-festival of free concerts, workshops and new music, the organisers are promising a little intriguingly what they are calling “bite-sized pieces,” presumably guaranteed Luis Suárez-proof. Backed by the PRS for Music Foundation the overall idea is to provide a platform for talented composers, performers and organisations who don’t exactly conform to mainstream norms of music-making but challenge our notions of what New Music is all about. Improvising piano trio Bourne/Davis/Kane are one of the groups taking part, in March having premiered composer Piers Hellawell’s ‘Sound Carvings, Strange Tryst’ at the Brilliant Corners festival in Belfast as part of the Biennial’s ongoing series of concerts. They play the Front Room of the Queen Elizabeth Hall at 6.15pm on Friday 4 July. The same evening in the QEH in another of the weekend’s highlights there is a premiere of a new vocal work from Shingai Shoniwa of the Noisettes and The Invisible’s David Okumu inspired by their shared African heritage.
