Unlike the only other reviewer of this product, who i think may have been mistaken about which product he was reviewing, I found nothing at all humorous about this MUSIC BOOK. It is an impressively accurate songbook of the album Diary of a Madman. Randy Rhoads, the guitarist on Ozzy's first two solo albums (the other one being Blizzard of Ozz) was quite a virtuoso and his style influenced many as he successully wove his classical influences into Heavy Metal. Along with Eddie Van Halen, he is one of the first guitarists to popularize the two-hand tapping technique, as most famously demonstrated on Blizzard's "Crazy Train" or as transcribed here in the solo to "Flying High Again." It is not possible to transcribe every single sound evoked from the guitar (on "Believer" it notes that random scrapes and various sounds are produced), but this book comes as close as can be expected. Students of classical guitar will find the title track to be of interest for study as it is the most classically influenced of Rhoads's work with Ozzy.
