Book excerpt: Jethro Tull was one of the truly innovative rock bands to emerge from the late 1960s. At their peak the idiosyncratic group, fronted by multi-instrumentalist Ian Anderson, resembled a troupe of roving English minstrels. Crafting a signature progressive rock sound that resisted easy categorization, they were often derided by critics as too British, too eccentric, too theatrical. Over the span of a decade, Tull released a string of sublime albums featuring intricate compositions in a wide range of musical styles, with little regard for the showbiz maxim "give the public what it wants." Focusing on the years 1968-1980, this history includes insider accounts based on exclusive interviews with key members and rare photographs from Ian Anderson's personal collection.
