While overseeing the soundtrack for T2 Trainspotting, Underworld's Rick Smith arranged a meeting with Iggy Pop in a room at the Savoy Hotel on London's Strand to discuss working on collaborative music for the film. The thread that had connected the artists previously was that Pop's "Lust for Life" and Underworld's "Born Slippy (Nuxx)" had both been in the original Trainspotting. The 4-track EP Teatime Dub Encounters is the result of a few clandestine hotel room recording sessions, that began a few weeks after Underworld and Iggy Pop had each released their last albums (Barbara, Barbara We Face a Shining Future and Post Pop Depression respectively) on the same day (March 18, 2016). It's neither historical or a tribute to past work. It' rather the work of artists in motion, engaged in a process that both bring to all of their work – one that uses spontaneity as a spur for creativity.
