Anna Meredith takes us on a toy train journey that doesn't run out of steam

Sometimes, the joy of watching a well-made film is not noticing the craft involved and instead being taken away by the narrative and emotional resonance. 

However, sometimes seeing the level of ingenuity essential in the construction of the piece is a joy-making element itself, the dedication and intricacy visible on-screen triggering the same endorphins as a well-timed gag or musical flourish.

In his latest promo, for British composer and performer Anna Meredith's instrumental track Paramour, Ewan Jones Morris has put the joy of construction at the forefront, taking us on a toy-train-mounted journey around musicians, instruments and knick-knacks.

Systematically plotted, with the labyrinthine construction managing to match the music's rises and falls impeccably, this 5-minute journey is less a ponderous commute and more a laid-back rollercoaster through the song itself. Grab a ticket and get on board!
