Stratus, was a short-lived English melodic hard rock supergroup. It was formed by ex-Iron Maiden drummer Clive Burr, the Troy brothers from then-inactive Praying Mantis; plus ex-Grand Prix vocalist Bernie Shaw and keyboardist Alan Nelson. The band split after only one album, Throwing Shapes, released first in Japan in November 1984 and elsewhere in 1985. Bernie Shaw became the lead vocalist for Uriah Heep the following year.
