Tomorrow Never Knows takes us back to the primal scene of the 1960s and asks: what happened when young people got high and listened to rock as if it really mattered—as if it offered meaning and sustenance, not just escape and entertainment? What did young people hear in the music of Dylan, Hendrix, or the Beatles? Bromell's pursuit of these questions radically revises our understanding of rock, psychedelics, and their relation to the politics of the 60s, exploring the period's controversial legacy, and the reasons why being "experienced" has been an essential part of American youth culture to the present day.
