I read the phenomenal unofficial biography As Above, So Below by Anders Tengner during the summer. It's based on interviews with the musicians and others who been close to Yngwie. It maps out Yngwies insane behaviour during the years, the failed commercial success but also the dedication and love for the music he become a pioneer in. I can't recommend it enough, it's a both fascinating and depressing read. So what better time than to listen through his discography?
