Ozzy Osbourne has been shown what a useless layabout his own son Jack is, after being joined onstage by a 10 year old for an epic shredding session on his track ‘Crazy Train’. Yuto Miyazawa is a guitar prodigy and has been an occasional guest on stage with Ozzy. Channelling the powers of Randy Rhodes and Zakk Wyylde, this kid can shred and sure puts Jack Osbourne’s tantrums and prescription drug addictions to shame. Check him shredding on stage with Ozzy last weekend in Hartford, Connecticut.
