Very serious.
Jeff Beck was great in the '70s blow by blow, Wired.....live with Jan Hammer etc....
Then Eddie Van Halen , Randy Rhoads, Joe Satriani and all the game changers came along and he fell by the wayside like most other guitar players.
His level of playing peaked about 40 years ago he hasn't gotten any better..... how is he supposed to follow the likes of Randy Rhoads, Brad Gillis, Jake E Lee and Zakk Wylde ? Even Tony Iomi .....
Jimmy Page Eric Clapton Jeff Beck all those guys have their place in history.... but I don't see call Jeff Beck fits in with Oz
I don't think he could even play the rhythm part of most Ozzy songs much less the leads
