“We’re literally shaking lazers with music,” says Lewis Roberts, the young British musician and composer known as Koreless. “It’s about intense, beating frequencies; a really physical relationship between sound and light.” The Well is Roberts’ immersive performance collaboration with visual artist Emmanuel Biard, a touring show incorporating the almost savant style of calculated, pulsating electronics — as heard on Koreless’ Yugen EP and forthcoming “TT / Love” split 12" on Young Turks — with Biard’s lazer mirror installation.

“Russian singers are famously very good at bottom end,” says Roberts of the extremely low voiced choir that feature in Simon Halsall’s film. The London-based director recently shot the Jamie xx music video for “Loud Places,” before capturing Koreless and Biard at the Future Everything festival in Manchester. “The low voices vibrate the mirror in a different way to what we would have done with synths. For the Sónar show we're going to strip it back to the physical bare essentials, as you can never make a choir as loud as you can blast direct sound on stage.”

The Well by Koreless and Emmanuel Biard is being performed today at Sónar by Day, Sónar Festival, Barcelona.
