Jethro Tull frontman Ian Anderson is releasing a new album, Homo Erraticus, on April 15 via his own Calliandra Records. The LP continues the story of Gerald Bostock, a fictional character Anderson created for Jethro Tull’s 1972 concept album Thick as a Brick. A U.K. tour will follow the release, and Anderson will hit the road in the U.S. this Fall.

Homo Erraticus picks up Bostock’s story where it left off on Anderson’s 2012 solo album, Thick as a Brick 2. The new record examines key events in British history, with stories told through various malaria-stricken, delusional characters, including Prince Albert.

The U.K. tour will feature Anderson and his band—guitarist Florian Opahle, bassist David Goodier, keyboardist John O’Hara, drummer Scott Hammond and singer Ryan O’Donnell—performing _Homo Erraticus_ from start to finish. The set will be followed by an array of Jethro Tull classics. The tour dates will be revealed in the near future.
