Led by flautist-guitarist/singer/songwriter Ian Anderson, Jethro Tull creates a mix of hard rock, blues and folk for a unique style that defies easy analysis; this has not, however, dissuaded fans from giving them 15 gold and 5 platinum albums. Now, as the band embarks on their 31st year, 1999 brings the return of their #1 LP from 1972, Thick As a Brick. This thematically dense concept album reappears with 2 bonus tracks: A live "Thick As a Brick" medley from 1978 and group interview.
