Steven John Wilson (born 3 November 1967) is an English music composer, most associated with the progressive rock genre. Currently a solo artist, he became known as the founder, lead guitarist, singer, and songwriter of the band Porcupine Tree, as well as being a member of several other bands. He has also worked with artists such as Opeth, King Crimson, Pendulum, Jethro Tull, XTC, Yes, Marillion, Tears for Fears, Roxy Music, and Anathema.
Wilson is a self-taught producer, audio engineer, guitar and keyboard player, playing other instruments as needed, including bass guitar, autoharp, hammered dulcimer and flute. Despite being mainly associated with prog music, his influences and work have encompassed diverse genres such as psychedelia, pop, extreme metal, electronic, and jazz, among others, shifting his musical direction through his albums. His concerts incorporate quadraphonic sound and elaborate visuals.
In a career spanning more than 30 years, Wilson has made music prolifically and earned critical acclaim. His honours include four nominations for the Grammy Awards, twice with Porcupine Tree, with his collaborative band Storm Corrosion and as a soloist on one occasion. In 2015, he received three awards at the London Progressive Music Awards for his services to the world of progressive rock music and crowned "the king of prog rock". Nevertheless, his work has largely stayed away from mainstream music, being described by publications such as The Daily Telegraph as "the most successful British artist you’ve never heard of."
