The Zealot Gene is the 22nd studio album by the British rock band Jethro Tull, released on 28 January 2022 by Inside Out Music. Nearly five years in production, it is their first studio album since The Jethro Tull Christmas Album (2003), and their first of all original material since J-Tull Dot Com (1999), marking the longest gap between the band's studio albums.

Songs from the Wood is the tenth studio album by British progressive rock band Jethro Tull, released February 1977. The album signalled a new direction for the band, who turned to celebrating British pagan folklore and the countryside life in a wide-ranging folk rock style which combined traditional instruments and melodies with hard rock drums and electric guitars.

In 1974, Jethro Tull announced plans for WarChild, a multi-faceted project that was to encompass a feature-length film, a soundtrack album, as well a new album from the band. In October of that year, Tull released a 10-song album that would climb to #2 in the U.S. and the top 15 in the U.K., but the film and accompanying soundtrack were shelved. To commemorate the 40-year anniversary of this ambitious experiment, Parlophone will revisit WarChild with several releases.

Homo Erraticus is the sixth studio album by British progressive rock musician Ian Anderson, former frontman of Jethro Tull. Released on 14 April 2014, Homo Erraticus is a concept album, loosely connected to Jethro Tull's Thick as a Brick (1972) and Anderson's Thick as a Brick 2 (2012), since it again credits the lyrics to the fictional character Gerald Bostock.
