From 1987 to 1990, Sugiyama continued to compose for various other Enix games. In 1991, he introduced a series of video game music concerts, five in all, called the Orchestral Game Concerts, which were performed by the Tokyo City Philharmonic Orchestra and Tokyo Symphony Orchestra. The performances included over eighteen different video game composers, such as Koji Kondo, Yoko Kanno, Nobuo Uematsu, Keiichi Suzuki, as well as Sugiyama himself. These concerts were held from 1991 to 1996; during this time, Sugiyama composed for other video games and arranged for some of them to be performed in the Orchestral Game Concerts.
