Ace of Diamond
To celebrate their 20th anniversary, Glay released their 26-song 2CD+DVD "Hai to Diamond Anthology" in May 2014, which included remixed and remastered versions of previously-released songs as well as demo tracks, radio show recordings, and music videos from their indie era. The band's October double-A-side single, "Hyakka Ryoran"/"Hashire! Mirai", included the third opening song for the anime series "Ace of Diamond," and in November, they released their thirteenth album "Music Life", which was also available as a 2-disc limited edition including the bonus CD "Ballade Best Melodies," featuring their best ballads selected by fan voting. "Music Life"'s cover image was inspired by The Beatles album "Revolver".
