Tull restrains its tonality to basic chord changes and folk-song melodies. But the rhythms are lavish–particularly the instrumental arrangements, where no two players are allowed the same part.

Heavy Horses is merely the followup to last year's Songs from the Wood, which may well have been the group's best record ever. Anderson warns that this is the end of the folk-tinged Tull, that the band will return to boogie forthwith. That's a pity because this genre has suited Jethro Tull wonderfully. (RS 274)
