Aina was a German progressive metal project produced by Sascha Paeth with a number of guest appearances including Glenn Hughes, Michael Kiske and Candice Night. It resulted in the metal opera Days of Rising Doom, which was released in 2003 by Transmission/The End Records. The concept was created by Amanda Somerville who also wrote the lyrics. The music was composed by Robert Hunecke-Rizzo. Ten years after its release, Paeth indicated that there were no plans to revisit the project.
