Album Crest of a Knave (Jethro Tull). Songs and videos online

Crest of a Knave is the sixteenth studio album by British rock band Jethro Tull, released in 1987.

The album relied more heavily on Martin Barre's electric guitar than the band had since the 1970s. However, several tracks still featured drum machine instead of a live drummer. Keyboardist Peter-John Vettese was now absent and it was Ian Anderson who contributed the synth programming. The album sleeve only lists Ian Anderson, Martin Barre and Dave Pegg as official band members. The cover was designed by heraldic artist Andrew Stewart Jamieson.

The album was a critical and commercial success. It went on to win the 1988 Grammy Award for Best Hard Rock/Metal Performance Vocal or Instrumental, beating the heavily favoured ...And Justice for All and critics' choice Nothing's Shocking. The award was highly controversial as many did not consider the album or even the band to be hard rock or heavy metal. Under advisement from their manager, no one from the band turned up to the award ceremony, as they were told that they had no chance of winning. In response to the controversy, the band's record label Chrysalis took out an advert in a British music periodical with the line, "The flute is a heavy, metal instrument!" In 2007, the win was named one of the 10 biggest upsets in Grammy history by Entertainment Weekly.

The style of Crest has been compared to that of Dire Straits, in part because Anderson no longer had the vocal range he once possessed (the result of recent throat surgery). Tull's frank treatment of sexuality was unabated, however. The album contains the popular live song "Budapest", which depicts a backstage scene with a shy local female stagehand.
