Edguy is a German power metal band formed in 1992 in Fulda by students Tobias Sammet, Jens Ludwig, Dominik Storch, and Dirk Sauer. Initially named after their math teacher, the band faced early rejections from record labels but persevered, releasing their unofficial debut album, Savage Poetry, in 1995. They gained wider recognition with their subsequent albums, including Kingdom of Madness (1997) and Vain Glory Opera (1998), featuring guest appearances from notable musicians. Over the years, Edguy has evolved their sound, with Sammet also launching the successful metal opera project Avantasia. The band has released multiple studio albums, including Age of the Joker (2011) and Space Police: Defenders of the Crown (2014), and has engaged in extensive touring.
