Book excerpt: For as long as people have been migrating to London, so has their music. An essential link to home, music also has the power to shape communities in surprising ways. Black music has been part of London's landscape since the First World War, when the Southern Syncopated Orchestra brought jazz to the capital. Following the wave of Commonwealth immigration, its sounds and styles took up residence to become the foundation of the city's youth culture. Sounds Like London tells the story of the music and the larger-than-life characters making it, journeying from Soho jazz clubs to Brixton blues parties to King's Cross warehouse raves to the streets of Notting Hill - and onto sound systems everywhere. As well as a journey through the musical history of London, Sounds Like London is about the shaping of a city, and in turn the whole nation, through music. Contributors include Eddy Grant, Osibisa, Russell Henderson, Dizzee Rascal and Trevor Nelson, with an introduction by Soul2Soul's Jazzie B.
