On "Ecstasy"s supporting tour My Bloody Valentine conceived the idea of "the holocaust", an interlude of noise and excessive feedback during live performances which was later attributed to their song "You Made Me Realise" and often exceeded 130 decibels. The band toured small student venues and, according to Kevin Shields, at "one particular place, there were these guy playing pool in the background, shouting amongst themselves and being quite loud and not paying attention". Before performing "Clair", Shields said to the band "let's just do it until those guys stop" and performed a two-chord riff in the song that lasted for an approximate 30 minutes.
