Sky 4: Forthcoming is the fourth studio album by English/Australian instrumental progressive rock band Sky, released in 1982. It is the only Sky album to contain no original compositions - except for Kevin Peek's rewrite of a 13th-century melody - relying instead on the band's arrangements of other (mostly classical) composers' pieces.
In 2015 Esoteric Recordings continued a schedule of remasters and expanded releases with this recording.
