In 1984, Jethro Tull released Under Wraps, a heavily electronic album with no "live" drummer and instead, as on Walk into Light, a drum-machine was used. Although the band were reportedly proud of the sound, the album was not well received. However, the video for "Lap of Luxury" did manage to earn moderate rotation on the newly influential MTV music video channel. As a result of the throat problems Anderson developed singing the demanding Under Wraps material on tour, Jethro Tull took a three-year break. Vettese quit the band after the tour, angry at critics for the bad reviews of The Broadsword and the Beast (1982), Walk into Light (1983), and Under Wraps(1984). During this hiatus, Anderson continued to oversee the salmon farm he had founded in 1978, although the single "Coronach" was released in the UK in 1986 after it was used as the theme tune for a Channel 4 television program called "Blood of the British".
Anderson, Barre, Pegg and Perry: the "hard rock" Tull (1987–1994)
Jethro Tull returned in 1987 with Crest of a Knave. With Vettese absent (Anderson contributed the synth programming) and the band relying more heavily on Barre's electric guitar than they had since the early 1970s, the album was a critical and commercial success. Shades of their earlier electronic excursions were still present, however, as three of the album's songs again used a drum machine, with Doane Perry and Gerry Conway sharing drum duties on the other tracks. Prior to the Crest of a Knave tour, keyboardist Don Airey (ex-Rainbow, Ozzy Osbourne, Michael Schenker Group) joined the band.
