Great musicians who should have been famous except....

I'm throwing this out there as an example. My 16 yr old aspiring drummer son asked me if I had anything in the vinyl collection tonight... apparently the U Tube video tutorials finally got boring. He is really good and practices non stop but it was refreshing when he asked about ideas for sound. In a moment of 30 years past clarity I put on the B side of Van Halen 1984… Is Alex Van Halen the most under rated rock drummer of all time? And is there a better lead in to ANY rock vinyl side than that???
