On the longer history of black music in Britain, I have drawn upon:
Lloyd Bradley (2013) Sounds Like London: 100 Years of Black Music in the Capital (London: Serpent’s Tail)
Charlie Gillett (1970) The Sound of the City (London: Sphere)
Paul Oliver (ed.) (1990) Black Music in Britain (Milton Keynes: Open University Press)
Jon Stratton and Nabeel Zuberi (eds.) (2014) Black Popular Music in Britain Since 1945 (Aldershot: Ashgate)
Soul Britannia, a BBC4 documentary: only the first of three appears to be currently available, at: https://www.youtube.com/watch?v=adFVkFv6oGE
Relevant work in Cultural Studies to which I refer includes:
Hugh Barker and Yuval Taylor (2007) Faking It: The Quest for Authenticity in Popular Music (London: Faber)
Paul Gilroy (1993) The Black Atlantic: Modernity and Double Consciousness (London: Verso)
Dick Hebdige (1979) Subculture: The Meaning of Style (London: Methuen)
Dick Hebdige (1987) Cut n’ Mix: Culture, Identity and Caribbean Music (London: Comedia)
Simon Jones (1988) Black Culture, White Youth (London: Macmillan)
In addition to Hebdige (1987) and Jones, Two Tone is well documented in Daniel Rachel’s Walls Come Tumbling Down (London: Picador, 2016), a compilation oral history of Rock Against Racism, Two Tone and the later Labour Party organization Red Wedge.
There are several memoirs written about Northern Soul, of which the most thoughtful is Stuart Cosgrove’s Young Soul Rebels (Edinburgh: Polygon, 2016). David Nowell’s The History of Northern Soul (London: Portico, 2015) also contains a considerable amount of first-hand recollection from fans. There are also several fan websites and YouTube channels.
Among a great many recent documentaries about Northern Soul, I have found the following particularly useful:
Keep on Burning, director Joe Boy, A2B Media, 2012 (on DVD)
Northern Soul: Keeping the Faith, BBC Culture Show featuring economics journalist Paul Mason, 2013: https://www.youtube.com/watch?v=JMtaEASd2LI
Northern Soul: Living for the Weekend BBC4, 2014: https://www.youtube.com/watch?v=dNAiKCWMv30
The Way of the Crowd, fan-produced documentary, 2004: https://www.youtube.com/watch?v=zWJOB79ZprQ&list=PLMIkFLeFlik2z0xkPtsNCmZ-HeVaIgFzc
There’s a YouTube playlist containing many more, mostly shorter clips at: https://www.youtube.com/playlist?list=PLMIkFLeFlik2z0xkPtsNCmZ-HeVaIgFzc
Soul Source is a large website with music, videos, news and discussions about soul broadly defined, but with a primary focus on Northern Soul: https://www.soul-source.co.uk/
Academic studies I have drawn upon here include:
Lucy Gibson (2014) ‘Nostalgia, symbolic knowledge and generational conflict’, presentation at Rare Records and Raucous Nights: Investigating Northern Soul, symposium at University of Salford, video at https://www.soul-source.co.uk/videos/view-271-nostalgia-symbolic-knowledge-and-generational-conflict/
Katie Milestone (1997) ‘The love factory: the sites, practices and media relationships of Northern Soul’, in S. Redhead, D. Wynne and J. O’Connor (eds.) The Clubcultures Reader (Oxford: Blackwell)
Tim Wall (2006) ‘On the floor: the politics of dancing on the Northern Soul scene’, Popular Music 25(3): 431-455
Andrew Wilson (2007) Northern Soul: Music, Drugs and Subcultural Identity (Cullompton, Devon: Willan Publishing)
Tony Palmer’s ATV documentary The Wigan Casino, in the series This England, is available on DVD and on YouTube: https://www.youtube.com/watch?v=TbEuq54FcBg
The two fictional films I discuss, Soul Boy (directed by Shimmy Marcus, Ipso Facto Films, 2011) and Northern Soul (directed by Elaine Constantine, Universal, 2014) are both available on DVD.
There is much less on the ‘southern soul’ scene. Aside from Lloyd Bradley’s book, I have also made use of:
Anthony Marks (1990) ‘Young, gifted and black: Afro-American and Afro-Carribean music in Britain 1963-88’, in Paul Oliver (ed.) Black Music in Britain (Milton Keynes: Open University Press)
Robert Strachan (2014) ‘Britfunk: black British popular music, identity and the recording industry in the early 1990s’, in J. Stratton and N. Zuberi (eds.) Black Popular Music in Britain Since 1945 (Aldershot: Ashgate)
I have also relied on a range of websites, videos and short articles, including:
AM/FM, website about the history of pirate radio in the UK: http://www.amfm.org.uk/
Caister Soul site: http://www.caistersoul.co.uk/index.php
Emma Brooker (1996) ‘Soul crazy after all these years’, The Independent https://www.independent.co.uk/life-style/soul-crazy-after-all-these-years-1347214.html
