This is an album commemorating the 10th anniversary. Pieces of music included in the album were produced, rearranged, remastered by TSUKINOSORA. TSUKINOSORA is an artist illustrating a world of endlessly fresh, creative sounds. In a single song, she can blend the melodies woven by her grounded, yet subtle and delicate piano style with ethnic and electronic instruments and orchestral sounds. In addition to composing and arranging, she works on practical recording and as an engineer, wearing three hats as artist, sound creator, and pianist. Her fastidious approach to sound—compromising on nothing up to the last sound that reaches the listener, never adhering to established notions like genre, and seeking a world of completely integrated art— is the driving force behind her creativity. TSUKINOSORA is involved in many forms of music creation, including TV and radio themes and background music, and video game and film scoring. One of her better-known songs, "Luv Letter", which she wrote, and on which she played piano, for DJ OKAWARI, was used as the exhibition program music for the 2009-10 Olympic season by Daisuke Takahashi, whose sterling accomplishments in the world of figure skating have made him immensely populareven after his retirement from competition. The song's delicate yet refined, made-in-Japan sound became an instant worldwide sensation.
