Tomorrow Never Knows
In his book "Electronic and Experimental Music", Thom Holmes includes "Tomorrow Never Knows" in his list of the "pioneering works" in electronic music. He credits the song with "usher[ing] in a new era in the use of electronic music in rock and pop music". Music historians David Luhrssen and Michael Larson say that with "Revolver" the Beatles "erased boundaries of time and culture", adding: "Ancient met modern on 'Tomorrow Never Knows' as sitars encountered tape loops. 'Tomorrow Never Knows' reintroduced the sustained repetition of the drone, absent in Western music since the Middle Ages and only recently discovered by avant-garde composer La Monte Young." According to Peter Lavezzoli, in his book "The Dawn of Indian Music in the West", "'Tomorrow Never Knows' was the most groundbreaking production to date in popular music" and he says it "still retains a terrifying visceral power".
