Once upon a time, 15 years before Underworld became dance legends and Born Slippy became the biggest song of the rave era, they were a very different band.

Formed at art school in Cardiff, they had no name, just a squiggly logo. But because it’s almost impossible to sell records when no one knows your name, the band with no name became Freur.

They looked absurd – a little bit like Sigue Sigue Sputnik crossed with A Flock Of Seagulls – because it was 1983 and that’s what pop groups looked like in those days, and their synth-pop single Doot Doot gave Karl Hyde, the singer, and Rick Smith, the synth player, their first minor hit.

They were apparently big in Italy, but nowhere else, so in 1987 one of them left and someone else joined and they became Underworld. Even then no one bought their first two albums, even though they supported Eurythmics on a US tour.

Then they met a bloke called Darren Emerson, a teenage City boy turned DJ, who joined the band and introduced them to dance music. Once they started going to raves Underworld found their people, and their place, and their sound.

But this was their sound and place in 1983: a place where silly hair and sillier outfits combined with silly sounds and a silly name to make a (minor) hit single.
