16. Steven Wilson, 'The Raven Refused to Sing (And Other Stories)'
After years spent remixing King Crimson, ELP and Jethro Tull records and decades fronting Porcupine Tree, art-rock firebrand Steven Wilson made his own prog touchstone with his third solo album, The Raven That Refused to Sing. As bandleader and coproducer (alongside Pink Floyd associate Alan Parsons), Wilson coaxed one of the most economical and soulful solos of all time from guitarist Guthrie Govan on "Drive Home" and encouraged Parsons to rig a wah-wah pedal backwards for some haw-haw guitar on "The Holy Drinker." The album is lush, heady and often exhilarating, but most important, it's progressive in the most literal way: Raven is Wilson's most advanced work to date.
