On May 21, 1993, Buck-Tick released the single "Dress", which was later re-released in 2005 and used as the opening theme for the "Trinity Blood" anime. Soon after, on June 23, Buck-Tick released their seventh studio album, "Darker Than Darkness -Style 93-" a loose concept album focusing on death. The album confused fans because after the last track (track 10), the CD skips and picks up at track 75, which began with strange buzzing noises and slowly evolved into another song. This technique was rare in Japan at that time, and apparently some fans tried to return their CDs to stores, claiming that they were broken. On this album, the band also began to experiment with different instruments — Hoshino played keyboards, and during live shows, Sakurai tried his hand at the saxophone. Both Sakurai and Hoshino played these instruments on the band's next album, "Six/Nine".
