Experiences? Mahavishnu Orchestra played at my local high school with their original lineup. Jazz metal, LAF.
Saw Charlie Mingus play a tiny club in Boston unamplified and tell the audience to sit down and shut up, or else.
Sun Ra gave me a stern scowl when I fell out of my seat laughing, about eight feet away from him. Then he decided it was cool and gave a little nod.
Went to see a show my friend was tech director for, couldn’t find him anywhere, but Jack Bruce walked up and chatted me up for a while and tried my bass that I had with me. He wasn’t billed but was part of the opening act.
Reverse scalped a ticket to see a show on Bowie’s Ziggy Stardust tour, five bucks got me in.
When I was in college Aerosmith used to play out on the sidewalk in front of the student union building pretty regularly, ca. 1971. Sounded exactly like Aerosmith, go figure.
I was lucky enough to see hundreds of killer rock and jazz shows all through the seventies and eighties; one big favorite was/is Pat Metheny, who I’ve never seen do a bad show. Other favorite shows were Jaco with Joni Mitchell, Duane Allman with Delaney and Bonnie, Ornette Coleman’s crazy mid-80s double trio, Pink Floyd doing Dark Side when it was still called Eclipse, that Sun Ra show in NYC with about a dozen sax players sitting in, Mountain at Fillmore East on NYE 1970, Faces with Ronnie Wood, Jeff Beck on the Wired tour at a country club venue, and King Crimson on the Lark’s Tongue, Discipline, and Beat tours, all three from fifth row or closer. Then there’s the DeadHead/jam band stuff I used to be into, what I can vaguely remember of that time…
Haven’t done an arena or stadium show in eons, it’s mostly smaller clubs or nothing for me in my geezer phase.
