There are bands, there are solo artists and there are collaborations. When one musician has an idea that cannot be executed by his or any other band, when he sees it big because there’s an entire story connected to it, featuring different characters and situations… then we’re dealing with an ‘opera’ here, or a ‘musical’ if you want. For this, several artists in different fields are needed (vocalists and instrumentalists), each adding their own touch. The 21st century has seen three big operas pop up, but we found a few more. Let the different stories, lyrics, compositions draw you inside and show you a wondrous world not often explored in Metal.
