The Hardy Tree has been played on NTS shows including Kit Records, with Looking Down On London first played on 13 May 2018.

The Hardy Tree is British musician Frances Castle, who previously recorded under the name Transistor Six.

The music on her 2010 debut album, 'The Fields Lie Sleeping Underneath', was inspired by Castle's local London neighbourhood. Recorded at home in an attic room over a year, she patched and stitched together an orchestral jigsaw puzzle of sounds that hint at audio memories from lost kids 70 TV programmes, ghost orchestras, cinema organs, folk song, and static and crackle.

In 2011 she set up the boutique record label Clay Pipe Music.

Her subsequent albums include "Through Passages Of Time" (2016), "Sketches in D Minor" (2017), Common Grounds (2022)
