Both of his parents are folk musicians. Mary Alice Amidon and Peter Amidon had a major influence on their son's development. Sam has a reputation for musical curiosity and stylistic openness. His self-released debut album Solo Fiddle in 2001 exclusively showcased traditional fiddle instrumentals. Amidon's unique artistry results from his extremely playful and experimental approach as well as his distinctive vocals and idiosyncratic intonation.
Sam Amidon currently lives in London with his wife and son, maintaining close relations with many international artists. He is one of the main signings to Bedroom Community, the Reykjavik-based record label collective founded by Valgeir Sigurðsson, Nico Muhly and Ben Frost. Bedroom Community released his second album All Is Well in 2008.
Amidon’s current album The Following Mountain appeared in 2017, on the Nonesuch label, and in contrast to earlier albums, solely showcases his own compositions.
Amidon works as a solo artist, but also engages in all manner of collective contexts ranging from street concerts to performances with symphonic orchestras.
