Crest of a Knave is the sixteenth studio album by British rock band Jethro Tull, released in 1987. The album was recorded after a three-year hiatus caused by a throat infection of vocalist Ian Anderson, resulting in his changed singing style. Following the unsuccessful electronic rock album Under Wraps, Crest of a Knave had the band returning to a more hard rock sound. The album was their most successful since the 1970s and the band enjoyed a resurgence on radio broadcasts, appearances in MTV specials and the airing of music videos. It was also a critical success, winning the 1989 Grammy Award for Best Hard Rock/Metal Performance Vocal or Instrumental in what was widely viewed as an upset over the favorite, Metallica's ...And Justice for All.

This album was released simultaneously on LP and on CD, but the vinyl edition did not feature the songs "Dogs in the Midwinter" and "The Waking Edge". Both tracks appeared on vinyl as B-sides to the singles. The album back cover shows in the credits that the album was "Recorded just round the corner from the kitchen in the room behind the door which used to be painted white but isn't any more". And also: "Martin would like to thank Paul Hamer (Hamer Guitars). Ian and Dave would like to thank almost everybody else." Musical style The album relied more heavily on Martin Barre's electric guitar than the band had since the 1970s. The style of Crest has been compared to that of Dire Straits, in part because Anderson no longer had the vocal range he once
