The Condition of Muzak is a novel by British fantasy and science fiction writer Michael Moorcock, published by Allison & Busby in 1977.

The chaos and decay that permeated Moorcock's A Cure for Cancer and The English Assassin has devolved further into a surreal Europe of splintered city states.

Jerry Cornelius, increasingly morphing into his role as Pierrot, has lost the power to change or even affect events and narrows his quest to an everlasting search for his true love, his sister Catherine.

Here we move through Mr Moorcock's obsessions, the serials of Fantômas, the Beatles, Bob Dylan, the Arthurian legend, through chronos-zones—behold the pun!—to bi-sexuality, with a small sideswipe at Stanley Kubrick on the way.

[4] Writing in The Observer, Angus Wilson called it "one of the most ambitious, illuminating and enjoyable works of fiction published in English since the war".
