Phenomena is a rock concept around a supergroup formed by record producer Tom Galley, Metalhammer magazine founder Wilfried Rimensberger and Tom's brother, Whitesnake guitarist Mel Galley. Contributors were leading rock musicians such as Glenn Hughes, Brian May, Tony Martin and John Wetton amongst others. In a cover story, run by Kerrang! magazine in 1985, Phenomena's production of rock songs based on a story line running through a whole album, attached to artworks and other multi-media aspects was credited for the "return of the concept album" in the 1980s.
