Nightwing
Although Nightwing is commonly associated with Batman, the title and concept have origins in classic Superman stories. The original Nightwing in DC Comics was an identity assumed by alien superhero Superman when stranded on the Kryptonian city of Kandor with his pal Jimmy Olsen. Drawing inspiration from Batman and Robin, the two protect Kandor as the superheroes Nightwing and Flamebird. Following the Crisis on Infinite Earths continuity reboot in 1985, Nightwing was re-imagined as a legendary vigilante from Krypton whose story inspires Dick Grayson's choice of name when he leaves behind his Robin identity.
Imaginaerum
Imaginaerum is the seventh studio album by Finnish symphonic metal band Nightwish. According to Nightwish songwriter Tuomas Holopainen, the album is a concept album that tells the story of an old composer who is reminiscing of his youth on his deathbed. The album was produced alongside the movie of the same name, directed by Stobe Harju, who previously directed Nightwish's "The Islander" music video, and the album and the film share the same themes and general story. It is their second and last album with vocalist Anette Olzon, and as of 2018 the last with drummer Jukka Nevalainen.
