While Aoi Teshima went to C&S music academy in Fukuoka, she began a music career as an amateur in 2003. In 2003 and 2004, she participated in a musical event "DIVA", which was held in Fukuoka, as part of a "Teen's Music Festival".
In March 2005, she acted in "Japan-Korea slow music's world" in South Korea and her performance was favorably received among the audience. Her performance attracted the attention of anime director Gorō Miyazaki. Toshio Suzuki was also very impressed when he listened to her demo version of Bette Midler's "The Rose"
On June 7, 2006, she finally released a song called "Therru's song" (テルーの唄 Terū no Uta?). This song was used in a film directed by Gorō Miyazaki Tales from Earthsea (ゲド戦記 Gedo Senki?). She also voiced Therru.
On July 29 of the same year, the film was shown in Japan after releasing her song.
She was featured singing for the theme song of a new Nintendo Wii RPG, Fragile: Sayonara Tsuki no Haikyo. The song is called "Hikari".
