33 Revolutions Per Minute

Why 33? Partly because that's the number of rotations performed by a vinyl album in one minute, and partly because it takes a lot of songs to tell a story which spans seven decades and five continents – to capture the colour and variety of this shape-shifting genre. This is not a list book, rather each of the 33 songs offers a way into a subject, an artist, an era or an idea.

The book feels vital, in both senses of the word: necessary and alive. It captures some of the energy that is generated when musicians take risks, and even when they fail, those endeavours leave the popular culture a little richer and more challenging. Contrary to the frequently voiced idea that pop and politics are awkward bedfellows, it argues that protest music

is pop, in all its blazing, cussed glory.
