Kid Icarus / Metroid Original Soundtrack Orchestra Version is a 7" two-sided single released on February 25, 1987, only in Japan. It is available in both cassette and vinyl form. The single's label is Fun House, and its catalog number is 07FA-1106. Containing six tracks arranged by Hirokazu Tanaka, with three for each game, the single features much of the music from both Metroid and Kid Icarus, re-arranged in a chiptune style. The second and fifth track on the single combine multiple themes from the respective game; in Metroid's case, Samus Aran's Appearance Fanfare, Brinstar (Metroid) and Escape, while Title (Metroid) and Ending (Metroid) appear as separate tracks. Norfair, Ridley's Chamber, the Chozo Statue/Elevator theme and Tourian are not included with this single.
All Metroid tracks are on side B of the single. Notably, the "uplifting" portion of the Escape theme, which is present in the Western NES version of Metroid but absent in the Famicom Disk System version, is included in the single's arrangement. This is the earliest Metroid-related musical release. It would later be followed by Super Metroid: Sound in Action, Metroid Prime & Fusion Original Soundtracks and Samus Archives Sound Selection.
The first track, Title Music, is 1:48 long; the second, Start Sound, Brinstar, During Escape BGM is 3:37, and the final track, Ending Music, is 2:17.
