Lust for Life (Trainspotting)

The drumbeat arrives before anything else — four bars of pure, metronomic insistence that feel less like an introduction than a challenge. Then the guitar tears in and the whole thing becomes a machine running at the edge of control: raw, propulsive, almost confrontational in its energy. Iggy Pop's vocal is a full-body performance, a ragged shout that treats melody as optional and conviction as everything, somewhere between a carnival barker and a man genuinely daring the world to knock him down. The song is a celebration of appetite — of being alive in the most physical, irresponsible, thrilling sense of the word — and it moves with the reckless velocity of someone who has decided consequences are someone else's problem. Produced in Berlin in 1977 by David Bowie, it sits at the hinge point between punk and post-punk, before genre lines hardened. Its use in Trainspotting is one of cinema's great acts of tonal irony: a song this ecstatic deployed against images of heroin addiction, the music capturing the chemical rush while the film supplies the aftermath. Play this when you need to feel something raw and unmediated — when clean and polished is exactly wrong.
