As Luna Sea resumed activities, until the band's disbandment, Sugizo collaborated in the studio with actress Miki Nakatani, and singers Miu Sakamoto and Vivian Hsu among others. On August 11, 1999, a compilation album titled "Grand Cross 1999", sponsored by Sugizo's record label Cross, was released, featuring many musicians with whom he had worked with before and many for the first time.
