Die Glasglocke
In 2013, Williams was commissioned by New Writing North to produce songs in celebration of 50th anniversary of the publication of Sylvia Plath's "The Bell Jar". She performed five of the resulting tunes – "When Nothing Meant Less", "Battleships", "The Mind Has Its Own Place", "Tango With Marco", and "Part Of Us" – at the 10th Durham Book Festival. Teaming up with Ed Harcourt as producer, she released "Hypoxia" on 15 June 2015.
