"For me this is possibly the greatest rock album of all time. It's a band playing at the absolute, height of their power. It's very ambitious: it's got elements of ska and funk, pop songs, soul, jazz, rockabilly, reggae - and in the end it's got this really great blues energetic vibe. It just seems like they tossed it off and lyrically it touches on a lot of different subjects. Some of the songs are very political: 'Spanish Bombs' is about the Spanish civil war, 'London Calling' itself - that song is such an anthem. The band had some commercial success after this album - with Combat Rock - but to me London Calling is the pinnacle of their song-writing. It is just a fantastic record with an iconic sleeve; that shot of Paul Simonon smashing his bass, it's just incredible. I saw The Clash play in Chicago when I was on tour and it was like electricity. They came out and they started with 'London Calling'. The place was rammed with 5,000+ people and it went OFF! It was as if a bomb dropped and it was one of the most exciting concerts I've ever seen!"

"There's A Riot Goin' On is an abstract, nihilistic, urban death funk record. Sly documents the times better than anybody – 1971: the whole civil rights movement has been crushed by the murders of Martin Luther King, Bobby Kennedy and the whole American state dismantled the Black Panther party. Sly Stone documents the dread and the suffocation of those times. His music before that was transcendent and joyous with stuff like 'Everyday People', which was basically life-affirming music. Then from about 1969, '70, he starts to become darker with these new funk sounds. Even the hit single from the record, 'Family Affair', is dark. He would have never written that four years prior. It was like the utopian idealism of the '60s had gone and America was almost at war with itself. But Sly never made this a political record – his aim was to put the American flag on the cover with no writing on it. The lyrics were internalised, it was kind of like a closed-off, looking-inward record. There's no reverb on this record and it's completely dry. There's no real joy in the record."
