Homo Erraticus

Homo Erraticus is the sixth studio album by British progressive rock musician Ian Anderson, who is also the 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.

The album was released in four formats: as a double vinyl, a single CD, a CD + DVD collection, and an Amazon.com exclusive box set edition, containing the album on CD as well as three bonus discs.

Anderson and his band embarked on a promotional tour of the album, in which they performed the entire album for the first half of each show, and the best of Jethro Tull for the second half.
