On October 16th 2011, Marconi Union created an eight minute track, ‘Weightless’ in collaboration with the British Academy of Sound Therapy. In a scientific study commisioned by the Radox, it was labelled as the “most relaxing song ever”. According to scientists at the renowned Mindlab Institution it induced a 65 per cent reduction in overall anxiety and brought test subjects resting pulse rates to a level 35 per cent lower than their usual resting rates. The song features guitar, piano and manipulated field recordings. It is punctuated throughout by low tones that supposedly induce a trance-like state. This propelled the band into the media spotlight and news reports, and was reported in newspapers worldwide to be The Most Relaxing Song Ever.
Characteristically, MU declined almost all requests for interviews with the exception of a brief interview with Jarvis Cocker, during which they explicitly stated that they refused to make any claims about the so called therapeutic properties of the track, their interest in the project had been limited to the process of writing it in collaboration with the sound therapy professionals and they had set about making a piece of music they liked. They had taken no part in the testing, and that all the claims made about Weightless came from scientists and the media. Since then they have reverted to type and declined all further interview requests.
