Ali Project (typeset as ALI PROJECT) is a Japanese band with a strong Japanese Aristocrat-style image, consisting of Arika Takarano (宝野アリカ) and Mikiya Katakura (片倉三起也).
In the band's earlier days, their musical style tended towards light, cheerful and/or refreshing songs. However, the sound has changed in recent times to take on a darker and more mysterious tone. Takarano Arika, lead singer/lyricist, has termed this change as a transition from White Alice (白アリ) to Black Alice (黒アリ). Though there has been a general shift towards performing songs in the "Black Alice" phase, Ali Project has occasionally sung in the White Alice style as well.
In 1988 they made their indie debut in the chartsas Ari (Ant) Project (蟻プロジェクト) with their album Fantastic Garden (幻想庭園 Gensou Teien). The album was later included in Tatsumi Takayuki's book Philosophy of Progressive Rock (プログレッシヴ・ロックの哲学), which led to the band being classified under the progressive rock genre. Four years later in 1992 they changed their name and made their major debut with their single "Fall in love, maiden" (恋せよ乙女 Koi-seyo otome).
Most of their records are released by Toshiba-EMI, Victor Entertainment and Tokuma Japan. The band is notable in the anime community for having their songs featured in several anime opening and ending sequences, most notably the series Noir and Rozen Maiden.
