神楽 originally started out in 1998 as a band called ＣＲＯＷ under Key Party records. They released 1 mini album and a live DVD during this time, and toured with their 'brother band' Lar~Mia. CROW were known as the "Black feathers" and Lar~Mia the "white feathers". It was during this time that they wrote the popular song Hyakki Yakou. After being very successful, CROW changed their name, their record label, and left their 'brother band' behind.
