With a discography that spans around two dozen original albums and goes back as far as 1968, Ian Anderson's Jethro Tull are a true institution of British rock, having played a variety of styles throughout their extensive career, from blues-rock to jazz fusion, later crossing folk, heavy and even classical music to create their own vision of what has become known as progressive rock or symphonic rock, a current of which they are one of the exponents. At the Coliseu they'll be presenting a new album, "The Zealot Gene", released in 2022.
