Musea collaborates also with Finnish progressive rock magazine Colossus to produce progressive rock concept albums based on literary
masterpieces, inviting bands and artists from all over the world to collaborate. Example of this production are Kalevala, a 3CD opera
published in 2004, a three multi-disc boxsets dedicated to each of the canticas of the Divine Comedy - Inferno (2008), Purgatorio (2009)
and Paradiso (2010), or the album The Tales of Edgar Allan Poe - A Synphonic Collection (2010). Many artists collaborate with these
productions, among notable musicians like Marco Lo Muscio and Guy LeBlanc, or progressive band like Museo Rosenbach, Dunwich and
Twenty Four Hours.
