Stormwatch (1979) is an album by the rock group Jethro Tull - the third in a trilogy of albums mixing traditional British Isles folk harmonies with more conventional pop rock music. The album deals with the deterioration of the environment, warning of an apocalyptic future if mankind does not cease its drive for economic growth and pay attention to nature. Indeed, it is the last stage of the growth of pessimism following the hope of Songs from the Wood and the darker view of Heavy Horses.
