Using samples as his source, Tiersen has resampled, reprogrammed and recomposed audio to create entirely new tracks unrecognisable and decontextualised from their original versions.

In 2023, Tiersen collated Kerber and a new solo piano recording of the album alongside 11 5 18 2 5 18 and an album of remixes and reworkings from the likes of Terence Fixmer, Beatrice Dillon and Laurel Halo, as well as remixes by Tiersen of NEU!, Keeley Forsyth, Michael Price and Simon Fisher Turner & Edmund de Waal for a 4-disc box set, Kerber Complete. The release coincided with a unique tour that Tiersen and QUINQUIS embarked on, travelling on their sailboat, Ninnog - named after a medieval mother superior, who travelled from Wales to Brittany becoming a protector of women and a champion of sustainability and forestry – to a series of performances in Ireland, Wales, Scotland, England and the Faroe Islands.

A tour in early 2024 will continue some of the themes of the Ninnog tour. With focus on making personal connections, and finding the people and places that would be impossible within the constraints of a usual tour, Tiersen will journey across Europe solo in his campervan, avoiding motorways, stopping to play in rural towns and villages alongside the announced dates in more traditional venues, and he plans to make arrangements to eat at a friend, promoter, venue owner or fan’s home each day.
