Davy Knowles (born 30 April 1987) is a Manx blues guitarist and singer. Knowles currently tours as a solo artist, but is formerly of the blues-rock band Back Door Slam, as well as working under the name Davy Knowles and Back Door Slam for a short period of time. With Back Door Slam, he played lead guitar and sang on their debut album, Roll Away. After a split-up with bassist Adam Jones and drummer Ross Doyle, Knowles released the first and only album under the name Davy Knowles and Back Door Slam, Coming Up for Air, on 19 May 2009. Knowles drew his musical influences from blues musicians that he grew up listening to such as Dire Straits, Peter Green, and Eric Clapton's Cream. Due to his home country's proximity to Ireland, Knowles has stated that his music also is influenced by the Celtic genre, which is noted to be present in the song "Roll Away". In April 2009, Knowles toured with British guitarist Jeff Beck on his American tour, where he was the opening act. He toured with Joe Satriani and Chickenfoot in the United States through December 2009. Davy Knowles toured with The Rhythm Devils in 2010.
Knowles released his first solo album, The Outsider, in 2014. He released his second solo album, Three Miles From Avalon, in 2016. He is currently based out of Chicago, Illinois and continues to tour in the United States regularly.
