Whales Alive is a 1987 album of improvisational duets and sometimes trios between Paul Winter, Paul Halley, and recordings of humpback whales. Winter and Halley also collaborate with Leonard Nimoy, who reads poems and prose from various writers, including D. H. Lawrence and Roger Payne. The audio recordings made of the whales for this recording were used in the Star Trek IV: The Voyage Home (Nov. 1986) movie (for which Nimoy directed and reprised his character Spock), featuring the whales nicknamed "George and Gracie".
