Jethro Tull are a British rock band formed in Blackpool, Lancashire, in 1967. Initially playing blues rock, the band later developed their sound to incorporate elements of hard rock and folk rock to forge a progressive rock signature. The band is led by vocalist/flautist/guitarist Ian Anderson, and has featured a revolving door of lineups through the years including significant members such as guitarists Mick Abrahams and Martin Barre, keyboardist John Evan, drummers Clive Bunker, Barriemore Barlow, and Doane Perry, and bassists Glenn Cornick, Jeffrey Hammond, John Glascock, and Dave Pegg.
The group first achieved commercial success in 1969, with the folk-tinged blues album Stand Up, which reached No. 1 in the UK, and they toured regularly in the UK and the US. Their musical style shifted in the direction of progressive rock with the albums Aqualung, Thick as a Brick and A Passion Play, and shifted again to hard rock mixed with folk rock with Songs from the Wood and Heavy Horses. After an excursion into electronic rock in the early-to-mid 1980s, the band won its first and only Grammy Award with the 1987 album Crest of a Knave.
