The music of the video games Final Fantasy and Final Fantasy II was composed by regular series composer Nobuo Uematsu, who would go on to be the exclusive composer for the next seven Final Fantasy games. Although they were composed separately, music from the two games has only been released together. All Sounds of Final Fantasy I•II, a compilation of almost all of the music in the games, was released by DataM/Polystar in 1989, and subsequently re-released by NTT Publishing in 1994. Symphonic Suite Final Fantasy, an arranged album of music from the two games by Katsuhisa Hattori and his son Takayuki Hattori was released by DataM in 1989, and re-released by NTT Publishing/Polystar in 1994. Final Fantasy & Final Fantasy II Original Soundtrack, another arranged album, this time by Nobuo Uematsu and Tsuyoshi Sekito, was released in 2002 by DigiCube and again in 2004 by Square Enix. The music was well received by critics; reviewers have praised the quality and power of the original pieces, and reacted favorably to the arranged soundtracks. Several tracks, especially "Opening Theme", "Main Theme" and "Matoya's Cave", remain popular today, and have been performed numerous times in orchestral concert series, as well as having been published in arranged and compilation albums by Square Enix and outside groups. Concept and creation When Uematsu was working at a music rental shop in Tokyo, a woman working in the art department for Square, which would later become Square Enix, asked if he would be interested in creating music for some of the titles they were working on, and he agreed. Uematsu considered it a side job, and he did not believe it would become any sort of full-time job. He said it was a way to make some money on the side, while also keeping his part-time job at the music rental shop. Before joining Square, he composed music for television commercials. While working at Square, he met Final Fantasy creator Hironobu Sakaguchi, who asked him if he wanted to compose music for some of his games, which Uematsu agreed to. Sakaguchi gave him a few instructions, such as that the game needed a "battle" music and a "town" music, but left the remainder of the composing to Uematsu, aside from informing him of the specific technical limitations of the Famicom. Several pieces from Final Fantasy I and Final Fantasy II have been reused in different forms
