English musician, zither-player and multi-instrumentalist, heavily influenced by traditional Finnish, Scots Gaelic and North Iberian musics.
He has several productive and successful live-performing alliances, all ongoing, including with long-time collaborator Ian Blake, with Armenian duduk player Tigran Aleksanyan, and with Canada-based Chinese pipa and gu-cheng virtuoso Liu Fang and Vietnamese dan bau master Pham Duc Thanh.

He and the musicians on his 9th solo album, The Unbroken Surface of Snow (Cloud Valley, 2011) – Armenian duduk master Tigran Aleksanyan, multi-instrumentalist Ian Blake and Finnish singer Sanna Kurki-Suonio – became the band SANS, releasing SANS LIve in 2014, and, with the line-up expanded by the addition of Sanna's daughter Erika Hammarberg as co-vocalist, in 2018 released the album Kulku (Cloud Valley, 2018).

His 10th solo album, Zithers (Cloud Valley, 2020) is entirely solo, featuring just two instruments, both of them – as the title suggests – zithers: the electrified 74-string chord zither that has been a key instrument for him throughout his career, and a more recent one of his own devising, the marovantele, which has 22 pairs of strings on each side.
