Stormwatch

Stormwatch (1979) is the twelfth studio album by the rock group Jethro Tull. It is considered the last in the trilogy of folk-rock albums by Jethro Tull (although folk music influenced virtually every Tull album). Among other subject-matter, the album touches heavily on the problems relating to the environment, oil and money.
In 2004, a remastered version of Stormwatch was released with four bonus tracks.
This is the last Tull album to feature the classic line-up of 1970s. Bassist John Glascock, suffering at this point from the effects of a cardiac infection that eventually led to his death, is only featured on three tracks ("Flying Dutchman", "Orion", and "Elegy"). Ian Anderson played bass elsewhere on the album while Dave Pegg played on the subsequent tour.
The instrumental piece "Elegy" was written by David Palmer.
