Pillowfish are a progressive folk duo comprising Tom Drinkwater (vocals, Irish bouzouki, guitar) and Helen Bell (viola and fiddle). Formed in mid-2005 in York, England, they released their first album, Common Knowledge in 2006. They are stylistically eclectic and draw on a variety of influences in their original material, which is mainly a mix of political song, whimsical absurdity and folk-influenced instrumentals. Drinkwater's acerbic vocal style seems to polarise reviewers, and has been likened to Tymon Dogg, Robin Williamson, and Ian Anderson.
