After Syd Barrett departed Pink Floyd, the band that he had co-founded and fronted became a rudderless ship, releasing a series of nebulous (though highly inventive) jam albums and taking on touring expenses that nearly bankrupted them. Their eighth album was a make-it-or-break-it proposition, and its timing could not have been better. Released in March of 1973, The Dark Side of the Moon quickly topped the US Billboard charts and took up residence there for over 700 weeks, selling over forty-five million copies to date. In Lunacy, award-winning music biographer John Kruth ("A fantastic writer"—Jim Jarmusch) delves into the making of this iconic record and considers why it continues to speak to generation after generation of music lovers around the world. Placing the album in its full cultural and musical context, Kruth provides an illuminating look at the ingredients of its great "sonic stew"—a mixture of musical styles from avant-garde electronic to jazz to classical, all of them contributing to its timeless originality. Lunacy features in-depth interviews with musicians, artists, DJs, and many others who have deeply personal relationships with the record, including a passionate astrophysicist, a leading brain surgeon's nurse (who has performed surgery while "Brain Damage" plays), and a woman who gave birth while screaming along to the Floyd's "Great Gig in the Sky."Packed with behind-the-scenes details and unexpected insights, Lunacy is not just another rock history rehash, but a celebration of a unique time and the music that made it great.
