Underworld and Iggy Pop, the two artists behind the most iconic tracks from the original Trainspotting soundtrack have finally come together in 2018 for ‘Bells & Circles’. Underworld unveiled the track on Saturday evening at BBC’s The Biggest Weekend festival in Belfast after teasing a big surprise in an interview with Lauren Laverne and Joe Lindsay earlier in the day.
