Jethro Tull formed in February 1968 from the ashes of two unsuccessful blues/rock bands of the era.

Ian Anderson brought his unique and innovative style of flute playing to a public raised on the guitar based British bands who courted acceptance at London's famous Marquee Club.

After their first tentative blues oriented album, titled "This Was," the group moved through successive records towards a more progressive sound, and with "Aqualung" in 1971 achieved their first real international level of success.
