When 17-year-0ld Danny Donelly got a bank loan to open a record shop and sell dancefloor-filling electronic music, he little knew how he would help revolutionise his town and dance music at large

In the early 1990s, the suburban town of Romford was known for three things. It was the home of the world’s best snooker player, Steve Davis. It was where people placed bets at Romford dog track, over a dinner of chicken in a basket. And for those in the know, it was where the UK’s best underground dance music was bought and sold.

That pedigree was immortalised by Romford’s most famous musical act, Underworld, with frontman Karl Hyde shouting the words “mega mega mega, going back to Romford” at the climax of 1995’s Born Slippy. Those words now form the title of a new exhibition in the town, Mega Mega: Romford’s Suburban Sound Revolution, which charts how this unglamorous but party-spirited backwater became an upstart rival to great dance music cities such as Manchester or Detroit.

A new documentary follows the Chicagoan from child trumpet prodigy to Gabriel-singing icon and DIY maverick. ‘Not everybody wants to see musical genius’, he says

At We Out Here festival in Dorset in August, thousands of people could be heard singing a trumpet melody as if it was a giant brass-band karaoke session. On stage was Peven Everett, performing a rendition of Gabriel, one of the most celebrated anthems in dance-music history. Co-created with producer Roy Davis Jr, the best-known version, which blew up in UK clubs in the mid-90s, is a spiritual garage-house track about the “archangel of love” that can bring both punters and DJs to tears.

But Everett is much more than one song. Damon Albarn of Gorillaz tells me that “Peven has a once-in-a-generation voice … he’s a great inspiration to us all.” We Out Here founder, Gilles Peterson says that the Chicagoan is, alongside Detroit’s Moodymann and Amp Fiddler, “the closest thing dance music has to a Prince-type figure”. A prolific multi-instrumentalist and one-man cottage industry, Everett’s catalogue spans more than 500 tracks, across house, neo-soul, hip-hop, samba and more.
