The melody is alternating dominant chords that promise to arrive somewhere, but instead take you to more dominant chords, so the result is that you are in a continued tension that never really resolves.
6/6

That way, it felt like even the film’s musical score would haunt the driver with the temptation to go for a piss.
5/6

Once these were decided, the music was built outwards from these sounds.
4/6

Before finding the melody or rhythm, the foundation was built with textures. Composers Guillermo and Daniel experimented with water droplets, hollow plastic thuds, sand, ticking clock elements.
3/6

Early on, we established that we wanted the music to take itself dead seriously, despite the film’s comedic premise. Much of the comedy comes from the juxtaposition of the more conventional thriller aesthetics and the silliness of the content.
2/6

1/6

A getaway driver must wait three minutes for a gang of burglars to return to his car before making their escape.

There’s just one problem...

He’s absolutely desperate for a piss.
