Rhoads is known for his heavy metal prowess and pioneering metal soloing styles, but much of that style was rooted in his deep interest in classical guitar. He constantly sought lessons from top classical players while playing with Ozzy, and his acquired skill in both classical and folk styles was evident in such tracks as "Dee", a brief instrumental piece written for his mother Delores on the Blizzard of Ozz album, and "Diary of a Madman," a complex mix of classical arrangements and hard rock styles, and the title track of Rhoad's final album.
I seriously doubt video of Rhoads playing "Diary of a Madman" even exists, but if someone does please send me a link! The best I can do for DOAMM is a Youtube "slideshow", with the original track playing while a picture slideshow plays. It's a commonly-used technique by people who have audio they want to get out to the public. This song is a metal masterpiece, because of its diverse mix of heavy metal and classical measures, complex arrangements and time signatures, and haunting solo, something the likes of which had rarely been heard before. It's a healthy mixture of minor scales, harmonic minor and blues in the key of A. The intro has been covered by many a guitarist, including Zakk Wylde, Ozzy's current guitar player and arguably the greatest guitar player alive right now.
I had to put this clip front and center, because it's one of the first true live shred sessions. This video came no later than 1979, because it's from his pre-Ozzy days playing with Quiet Riot. this video proves that Rhoads, along with Eddie Van Halen, is one of the first true pioneers of heavy metal shredding. He combined an extraordinary knowledge of music theory and styles with incredible "chops" (that is, how fluid he is while picking notes), which are seemingly flawless in this video. Check out at 2:26, where he channels Eddie Van Halen while tapping natural harmonics on the guitar to create a nice xylophone-like sound. Just like Eddie previously, I'd encourage everyone to check out as many Rhoads videos as you can. He's a true legend on guitar and deserves his spot among the all-time greats.
