Jethro Tull's Ian Anderson has released his most personal album to date, 'Curious Ruminant', which explores his own personal experiences and feelings. The album features a spoken-word track based on a poem he wrote for someone who was bereaved. Anderson, the only constant member of Jethro Tull, has been a prolific songwriter for over seven decades and prefers to write songs based on visual experiences rather than love songs. 'Curious Ruminant' is the band's 24th studio album and is part of a recent streak of releases, with a European tour scheduled from April to December.
