It's difficult to deny the infectious melodies of a simple flute. It's clean, it's crisp, it's modest, yet somehow powerful--and it’s one of the reasons that Jethro Tull rose to fame in the 1970s. Deriving its name from an 18th century farmer/inventor, the traveling minstrel rock group used a flute in nearly all of its well known songs and it became the instrument that the English band became best known for. With its hybrid of blues, folk and prog-rock, the five-piece band steadily built a following with its residency at the Marquee Club in London, and once the band opened for Pink Floyd in 1968, its reputation skyrocketed and garnered it a major record deal.
