Randy Rhoads

No one did more to bring the classical aesthetic to mainstream metal than the late, great Randy Rhoads, whose epic Vivaldi- and Paganini-esque solos on Ozzy Osbourne’s first two solo albums marked the golden age of baroque shred.

Of course, Rhoads’ acoustic side was equally hypnotic. Directly inspired by Leo Brouwer’s “Etude VI” from Estudios Sencillos, Rhoads’ layered intro to “Diary of a Madman” is an alluring, arpeggiated exploration of A major, A minor, and everything in between.
