Tolerant, playful, learned, London Calling vividly repopulates London with the voices of black and Asian writers who have lived there over the last three hundred years. Sandhu delights in the sheer variety of ways in which these writers have imagined the city, in all its gloss and squalor. From the 18th century, where Ignatius Sancho runs a grocers shop, and sends out a stream of lively gossipy letters to his many cultured friends such as the author Laurence Sterne; to the twentieth, where Samuel Selvon pens novels which use modernist techniques to capture and build on the vibrant speech rhythms and shifting life experiences of Caribbean migrants, Sandhu prizes those writers who have immersed themselves in the messiness and chaos of the metropolis. He prefers writers like Hanif Kureishi or Salman Rushdie, whose characters exploit city life to break down barriers and fashion themselves anew, provide sardonic comment on London through their wild antics, and challenge a narrowly linear form of writing. V.S. Naipaul, despite acknowledged literary triumphs in other works, is seen to 'step back prudishly' from London, and to criticise the city like a dreary 'pub bore'.
For Sandhu, black writing has been too often seen by its critics and even its supporters as 'emergency literature',in which the only value is journalistic reportage, or political agitation. He shows how black writers display a much wider range, indulging their imaginations, creating lasting literary achievements, mixing pleasure with a sense of the hardships which they faced. His writing is itself both colloquial and intense, rich in a diction rendering the heaped-up mixture and the snappiness he loves so much in those he studies.
Sandhu does not entirely convince in one assertion, that 'London has been good for those coming from the old Empire'. Too many slave traders, antagonistic London mobs, racist landlords, crumbling rooms and vicious slurs lurk in the texts he examines to allow him to claim this. However, in bringing to prominence the long history of black and Asian inhabitants of London, Sandhu's service is not only literary. Without hectoring,he shows the good, bad and ugly sides of life as they experience it down the years; and the good, bad and colourful characters among them, from dedicated fighters against slavery, through criminal enforcers, to real and fictional chancers and tricksters whose scams and hopes for a better future are morally ambivalent. In all, the book is a stunning debut, one in which Sandhu demonstrates both the verbal energy and the generosity of moral vision which he charts in his favourite authors.
