Former Ozzy Osbourne bass player Bob Daisley – who was a key part in establishing the Prince of Darkness' solo career – believes Diary of a Madman is one of the best representations of Randy Rhoads' electric guitar talents.
The title track to Osbourne's second solo record – and the last to feature Rhoads' dazzling chops before his untimely passing in 1982 – combined the guitar icon's well-documented love for classical guitar with a suitably maddening musical complexity. Randy's playing, as Daisley says, is at the heart of the song.
