The Final Fantasy Crystal Chronicles video game series consists of Crystal Chronicles, a spin-off of the main Final Fantasy series, its sequels My Life as a King and My Life as a Darklord, and their spin-offs, Ring of Fates, Echoes of Time and The Crystal Bearers. Crystal Chronicles, Ring of Fates, and Echoes of Time have had released soundtrack albums to date, and Crystal Chronicles and Ring of Fates each have an associated single. Kumi Tanioka is the main composer for the series, having composed the three released soundtracks as well as the music for My Life as a King and My Life as a Darklord. Hidenori Iwasaki is filling that role for The Crystal Bearers. Nobuo Uematsu, the main composer for the regular Final Fantasy series, contributed one track to the Ring of Fates soundtrack. Yae and Donna Burke sang the Japanese and English versions of the theme song for Crystal Chronicles, respectively, while Aiko sang the theme song for Ring of Fates.
Final Fantasy Crystal Chronicles Original Soundtrack was released by Pony Canyon in 2003, as was its single, "Kaze no Ne", and a promotional album Final Fantasy Crystal Chronicles - A Musical Journey. Final Fantasy Crystal Chronicles: Ring of Fates Original Soundtrack and the double A-side "Hoshi no Nai Sekai"/"Yokogao" were released by Pony Canyon in 2007. The latest release is that of Final Fantasy Crystal Chronicles: Echoes of Time Original Soundtrack by Square Enix in 2009. All the albums and the singles received generally positive reviews, although the Crystal Chronicles album was the most universally appreciated of the three soundtracks. Unlike the soundtracks to the numbered Final Fantasy games, no compositions from the Crystal Chronicles soundtracks have appeared in any compilation albums produced by Square Enix or any official Final Fantasy concerts. "Morning Sky", the opening theme for Crystal Chronicles, was played in the first Games in Concert performance in Utrecht, Netherlands on November 26, 2006.
