The debut record from nehan (an evening with nehan) is a technical feat that borders science fiction: led by Masaki Batoh (Ghost, The Silence), the avant-garde rock quintet improvises each performance off the rhythm of a 9hz brain wave emitted from a test subject in a deep hypnosis. Batoh — who's also an acupuncturist — had the idea for a machine that could generate sonic data based on brain waves back in 2010 after winding down work with Ghost. He used this machine to record the 2012 album Brain Pulse Music before forming nehan in August 2022 to fully explore the concept.
Their performance is initiated by a 9hz brain wave emitted from a testee who has been brought into a deep meditative state. nehan respond with gongs, typani, tabla and other percussion, crumhorn, bagpipes, oscillator and mellotron, passing tranformatively through a musical prism, from east to west, from traditional folk and classical to rock, jazz, and electronic.
