Anyone remember Haddaway? Or Dr Alban? These were flash-in-the-pan early-Nineties pop stars who combined European dance music with tints of R&B and Afro-Caribbean pop. Who'd have thought their sound would be the template for mainstream American pop for the early 2010s. From Black Eyed Peas to Jennifer Lopez, everyone's into low-calory trance-house cheese with a side order of gutless electro.
