Daniel Rachel’s excellent new book focuses on the links between music and politics in the 1980s.

Ostensibly an oral history of three epochal movements of the era – Rock Against Racism, 2 Tone and Red Wedge – ‘Walls Come Tumbling Down’ shows how these campaigns politicised a whole generation.

Fresh from his fine ‘Isle Of Noises’ tome which interviewed key British songwriters, Rachel opens his contacts book again to get telling contributions from Pauline Black, Dennis Bovell, Billy Bragg, Lloyd Cole, Elvis Costello, Jerry Dammers, Andy Gill, Junior Giscombe, Paul Heaton, Linton Kwesi Johnson, Tracey Thorn, Tom Robinson, Paul Simonon, Paul Weller and many more.

There are also many rare or never-before-published photos of the era by the likes of Pennie Smith, Jill Furmanovsky and Kevin Cummins.

The story starts on 5th August 1976 when Eric Clapton used a notorious Birmingham Odeon gig to lambast the audience, calling for ‘w*gs’ and ‘P*kis’ to ‘leave the country’ and pledging his support for Enoch Powell, the Conservative MP who eight years earlier had made the infamous ‘Rivers Of Blood’ speech.

Clapton’s shocking proclamations sparked the Rock Against Racism movement, a campaign also inflamed by David Bowie’s comments to Playboy magazine concerning Hitler and the rise of fascism.

This troubling era is picked over in immense detail, with various jaw-dropping artefacts: Clapton’s handwritten ‘apology’ letter to Sounds magazine is printed in full, and there’s also an extremely rare photo of Bowie’s ‘Nazi salute’ at Victoria station in May 1976 (as well as a new-to-this-writer explanation/apology from Bowie).

Black musicians and music-biz legends also comment with great candour about life in the UK during this period.

The 2 Tone movement attacked racism at its source while many artists under that umbrella also supported the Campaign For Nuclear Disarmament and Rock Against Sexism.

When Margaret Thatcher swept to a second term of office in 1983, bolstered by the Falklands War, a new pacifism emerged, typified by tracks like Elvis Costello’s ‘Shipbuilding’ and Heaven 17’s ‘(We Don’t Need This) Fascist Groove Thang’.

Later, as the miners’ strike took hold and Thatcher’s assault on socialism gathered pace, Paul Weller and Billy Bragg formed the Red Wedge movement which focused its attentions on ousting her in the 1987 General Election. It wasn’t to be, of course – although she did resign in December 1990.

The final section of ‘Walls Come Tumbling Down’ focuses on Dammers and various accomplices’ efforts to raise public awareness about the banned ANC, with high-profile singles and the famous 1988 Nelson Mandela 70th birthday tribute at Wembley Stadium, followed by his eventual freeing from jail on 11th February 1990.

Full of juicy details, potent memories of a far more passionate and politically-engaged era of pop music, and gripping, sometimes moving testimonies, this fascinating book outlines a period when youth culture demanded a voice.
