Blind Guardian singer Hansi Kursch wears his nerdery on his sleeve - his band has always drawn inspiration from classic fantasy like J.R.R. Tolkien and others. But they go deeper, too - their 2010 album At The Edge Of Time draws content from Robert Jordan's Wheel of Time series, John Milton's Paradise Lost, the video game Sacred 2, and more. There are few musicians as steeped in fantasy lore as this guy.
