Your first concert was to see who and when?

ELO at the Anaheim Convention Center in So.CA.  I believe it was 1976 or maybe early 77.  I was especially blown away when they did Roll Over Beethoven!   Couldn’t believe when the cellist were laying on they’re backs playing using they’re feet to hold the cello up in the air.  Was so good I can still see it.  
I think I saw Dave Mason shortly after that.  Would have been right after the Dave Mason Certified Live album came out.  In his prime then!

Reading everyone’s first concerts made me think of one thing.  Two amazing concerts I saw were Led Zeppelin’s last tour through the US at the LA Forum with John Bonham and The Who’s last tour through the US with Keith Moon, also at the forum.  Both drummers died soon after those concerts and it just made me think, I must have been the J.D. Vance of drummers!
