A deal on Tyrs?! You're killing me!
Couldn't pull the trigger, so as a distraction, I'll go another direction:
I'm a sucker for "concerts attended" threads!
First show (outdoors, Oakland baseball stadium, Day On The Green) - Jeff Beck, Tower of Power, Santana, Journey. Yes they did a "jam" at the end with Beck, Santana, and Neal Schon, which was not especially memorable.
Second show (indoors, the Cow Palace) - ELO, Firefall, Steve Hillage. Entering the back of the floor, the volume, the lights, and Hillage with flowing hair and flowing robes playing "space rock". Made much more of an impression than the stadium show. ELO's lasers shining into the audience off a mirror ball and off the polished, amplified cellos was the full-on 70s arena-rock extravanganza!
First Grateful Dead show (out of ~150) - Winterland. "From Egypt With Love". Hamza el Din opened. Then the Nubians (more flowing robes) did some complex rhythmic clapping that seemed to take forever before the pattern repeated. We tried to clap along (I recall a quote by Mickey Hart: Only our audience could clap in 13/7). By the 2nd Dead set I thought to myself: This isn't a "regular" rock and roll concert!
Most embarrassed to have seen: Jason Mraz, 11 times! The wife's brief crush. Kinda kidding about being embarrassed, a few of the shows were excellent.
The full list of bands/artists seen would be fewer than some, more than many, perhaps not interesting to most. But, I did attempt to compile a list of guitarsts I've seen. Following the name is a "known for" comment, since many that are important to me aren't household names. No, I didn't see all those configurations, IE: I didn't see Beck with the Yardbirds or Clapton with Cream or Blind Faith or Derek and the Dominoes...
