"The Ninth Wave" uses a great many textures to express the story: in the style of Alfred, Lord Tennyson's Arthurian poems, Bush pursues a vision quest, taking the listener through a death and rebirth. The warmth of familiar sleep is cut by dangerous speed, ice and frigid water, an otherworldly trial and judgement, an out-of-body limbo, and finally a vigorous emergence and grounding in life energy. The disparate musical elements of "The Ninth Wave" were described by Ron Moy as "classically prog" because of their evident experimentation, and because Bush wholly embraces European music traditions without a trace of American influence.
