Jethro Tull’s singer, flautist and composer, Ian Anderson, will play “Thick as a Brick I & II” at 7:30 p.m. Sunday, July 21, at the Murat Theatre in Indianapolis. Tickets are on sale now.

Jethro Tull’s era peaked with 1972’s “Thick As A Brick,” a 45-minute continuous piece of music charting the difficulties of a child growing up and confronting a frightening and unfair world.

“In the light of the Aqualung reviews I deliberately set out to do a concept album that would in essence be a bit of a parody of other people’s concept albums and grandiose progressive rock adventures. I thought let’s take this slightly arrogant and pompous way of writing and presenting music to an extreme, with the fiction of a then 10-year old boy having written the lyrics. Of course it’s preposterous and really quite silly, but it was the era of Monty Python, when that sort of surreal British humour was quite well embedded in the British psyche,” said Anderson.

The album was a world-wide success, including a number 1 spot on the American Billboard chart, and excerpts from the piece have regularly featured in Jethro Tull and Ian Anderson live shows.

Reserved seat tickets are $59.50, $49.50, $39.50 or $29.50. are available at the Old National Centre Box Office of online.
