Question: Which band is English folk, Sunday Driver or Autolux?
Context: Sunday Driver are a Cambridge and London based fusion band with English folk and classical Indian influences.  In 2009 they became popular within the UK Steampunk scene. Tudor Lodge is an English folk music ensemble, which was formed in 1968, featuring John Stannard and Roger Strevens.  The group started playing at the White Horse in Reading, England, and later made appearances at other clubs on the folk circuit.  In 1969 Lyndon Green replaced Strevens and within a year, they were joined by the American singer and flautist, Ann Steuart.  Tudor Lodge then toured the English folk circuit for over two years, playing at numerous venues, including the legendary Troubadour and Les Cousins clubs in London, where they played alongside artists including Ralph McTell, Al Stewart, Mike Cooper and John Martyn.  Tudor Lodge also played support for Genesis, Fairport Convention, or Steeleye Span. Cruel River is the second solo studio album by English folk singer-songwriter Steve Knightley.  Knightley had spent 2006 with Show of Hands, his duo with Phil Beer, recording, releasing and promoting their twelfth album together, "Witness", which saw the duo explore a worldbeat sound that departed from their usual English folk sound.  The album was a success with critics and most fans, although some were perplexed by its direction.  During a break in promoting that album with touring in early 2007, Knightley decided to record his first solo album since 1999.  Hiring regular Show of Hands collaborator Mark Tucker to co-produce the album with himself, Knightley recorded the album in Presshouse Studios, Colyton in February 2007.  The album explores a stripped-back, minimal English folk sound, similar to that of early Show of Hands.  Lyrically, the album tackles dark subject matter. The Full English launched in 2013 and is an ongoing English Folk Dance and Song Society (EFDSS) project to create a searchable digital archive of English folk song collections from the early 20th century, thereby preserving and improving the accessibility of these resources.  The project is supported by the Heritage Lottery Fund, The Folklore Society, the National Folk Music Fund and the English Miscellany Folk Dance Group.  An offshoot of the archive, also in 2013, was an album and concert tour under The Full English name by a collective of UK folk singers. "Seventeen Come Sunday" is an English folk song (Roud 277, Laws O17) which was used in the first movement of Ralph Vaughan Williams' "English Folk Song Suite" and a choral version by Percy Grainger (1912).  The words were first published between 1838 and 1845. Six Studies in English Folk Song is a piece of chamber music written by English composer Ralph Vaughan Williams in 1926.  It is a collection of six English folk songs set for cello and piano.  Each song follows the same format: presentation of the tune in the solo line, followed by a full iteration of the folk song in the piano with an ornamented solo line. Autolux is an American alternative rock band consisting of Eugene Goreshter (vocals, bass), Greg Edwards (vocals, guitar, piano) and Carla Azar (drums, vocals).  The trio formed in 2001 and have released three full-length albums, "Future Perfect" (2004), "Transit Transit" (2010) and "Pussy's Dead" (2016).  Their eclectic sound draws from post-punk, electronic music and krautrock. The folk music of England is traditionally based music, which has existed since the later medieval period.  It is often contrasted with courtly, classical and later commercial music.  Folk music has been preserved and transmitted orally, through print and later through recordings.  The term is used to refer to English traditional music and music composed, or delivered, in a traditional style.  English folk music has produced or contributed to several important musical genres, including sea shanties, jigs, hornpipes and dance music, such as that used for Morris dancing.  It can be seen as having distinct regional and local variations in content and style, particularly in areas more removed from the cultural and political centres of the English state, as in Northumbria, or the West Country.  Cultural interchange and processes of migration mean that English folk music, although in many ways distinctive, has particularly interacted with the music of Scotland.  It has also interacted with other musical traditions, particularly classical and rock music, influencing musical styles and producing musical fusions, such as British folk rock, folk punk and folk metal.  There remains a flourishing sub-culture of English folk music, which continues to influence other genres and occasionally to gain mainstream attention. The Unthanks (until 2009, Rachel Unthank and the Winterset) are an English folk group known for their eclectic approach in combining traditional English folk, particularly Northumbrian folk music, with other musical genres.  Their debut album, "Cruel Sister", was "MOJO" magazine's Folk Album of the Year in 2005.  Of their subsequent albums, eight have received four or five-starred reviews in the British national press.  Their album, "Mount the Air", released in 2015, won in the best album category in the 2016 BBC Radio 2 Folk Awards.  In 2017 they released two albums featuring the songs and poems of Molly Drake, mother of Nick Drake. Kate Anna Rusby (born 4 December 1973) is an English folk singer-songwriter from Penistone, Barnsley.  Sometimes called the "Barnsley Nightingale", she has headlined various British national folk festivals, and is one of the best known contemporary English folk singers.  In 2001 "The Guardian" described her as "a superstar of the British acoustic scene."  In 2007 the BBC website described her as "The first lady of young folkies".  She is one of the few folk singers to have been nominated for the Mercury Prize.
