Cyclone is the eleventh album by Tangerine Dream, and the first in their canon to feature proper vocals and lyrics. The mystical lyrics and rock flute of Steve Jolliffe on the first two tracks marked a turn toward progressive rock. The third track, however, is an extended Berlin School instrumental more in the vein of the title track from Stratosfear. The cover is a painting by band leader Edgar Froese that slightly resembles his cover for 1974's Phaedra.
Despite being much maligned over the years, Cyclone has been outsold by only five other Tangerine Dream albums in the UK. It reached No.37 in a 4-week chart run.
