The nagging synth riff at the beginning of Underworld’s Rez is one of my favourite moments in music. It’s like the end of Close Encounters (where the scientists and the mothership are playing notes at each other) taking place in a sweaty warehouse around 1992, only the scientists are all pilled up ravers and the UFO is a massive speaker stack. Brilliant. Listening to it yesterday set me thinking about other great riffs that aren’t played on electric guitars. There most be some more corkers out there. Synths, trumpets, thumb pianos, fiddles, kazoos… – lay them on me, groovers!
