Heavy Horses

Heavy Horses is the eleventh studio album by Jethro Tull, released on 10 April 1978. It is considered the second album in a trilogy of folk-rock albums by Jethro Tull, although folk music's influence is evident on a great number of Jethro Tull releases. The album abandons much of the folk lyrical content typical of the previous studio album, Songs from the Wood, in exchange for a more realist perspective on the changing world. Likewise, the band sound is harder and tighter. The album reached #19 on the Billboard 200 album chart, and peaked at No. 20 on the UK Albums Chart. The third album in the folk-rock trilogy is Stormwatch.
This album was the last studio album to feature John Glascock playing bass on all tracks.
