Definition:: In order to be eligible an artist must have either clearly performed in an English or Celtic folk style or must have been part of the English or Celtic folk scene. Artists from non-folk styles were considered if their music includes obvious folk influences but pure folk artists were given priority. Genres considered for this list include: folk rock, folk pop, folk baroque, celtic rock, celtic pop, celtic new age, folk punk, folk metal, alternative folk, progressive folk, psychedelic folk, freak folk, indie folk, neofolk, folktronica and folk-influenced singer/songwriter styles. The list is comprised of English, (Northern) Irish, Scottish, Welsh and Breton folk artists. It only includes artists who recorded from the second British folk revival onwards (i.e. post-World War II artists).
Criteria: The artists were ranked according to their influence and acclaim within English and Celtic folk circles. Influence and acclaim on other musical genres and mainstream popularity were also considered to a lesser degree.
