German producer and founder of electronic label Raster-Noton, Alva Noto, and Japanese Academy Award-winning pianist Ryuichi Sakamoto have been collaborating together for more than a decade, experimenting with the boundaries between music and noise, combining Sakamoto’s atmospheric, melancholy piano with Noto’s minimalist production and quietly pulsating beats.

Tomorrow, June 19, sees the duo play as part of Yoko Ono’s Meltdown festival at the Royal Festival Hall. The pair are known to mix multimedia art installations with their music on the live stage, creating an immersive audio-visual experience that explores their experimental and esoteric compositions, often placing most emphasis in the drawn out, structured silence between the notes rather than the notated instrumentation of the composition itself. Mostly playing with only the two of them on stage and syncing their sounds to create a perfectly balanced mix of live piano and well-placed samples and electronics, they manage to create subtle orchestration that can be classified as both music and art.

Their show at Meltdown will be one not to be missed, and tickets are still available here. However, not only do we have a pair of tickets for the set to give away to one lucky winner, but they'll also receive three pieces of vinyl from Raster Noton’s back catalogue:

r-n 131 senking. tweek (12" vinyl EP) r-n112 grischa lichtenberger. treibgut (12" vinyl EP) r-n115 kyoka. iSH (12" vinyl EP)
