Some impressive lists there, two that spring to mind

KISS Alive (1975)
Saxon - The Eagle has Landed (1982)

Oh yes, i agree with you, it was one of the first Iron Maiden things i heard, i was blown away

Simon & Garfunkel - Live in Central Park. Amazing concert.

I was! Liverpool Stadium recordings anyway (not the Brixton bits)

Ones I'd like to have been at...

The Who - Live at Leeds
Bob Dylan at Newport Folk Festival/ Dylan live at Budokan/ Dylan - Before the flood
Sunderland/ Croydon - Free Live
Rolling Stones at MSG - Get your Ya-yas out
Led Zeppelin - How the west was won
Leicester/ Manchester - Genesis live
Any of the gigs used for Crosby, Stills, Nash & Young - Four Way Street and The Doors - Absolutely live

Any of the gigs from the Bellowhead live - The Farewell tour album. I saw them in Liverpool on the 2nd leg of the tour earlier this year and they are/ were a sensational live act.

Springsteen - Hammersmith 1975
The Jam - final gig in Brighton
Van Morrison - It's Too Late To Stop Now tour / album
Sex Pistols / The Clash / The Buzzcocks - Screen on the Green

not actually released as a CD (was as an edited DVD) but Muse at Glastonbury 2004. Stunning gig full of energy. Looking forward to what they pull out this year

Depeche Mode - 101 (Pasadena Rose Bowl)

I saw Fleetwood Mac live for the first time last year, absolutely amazing, but I wish I'd been around to see their performances in the 70s and 80s.
A little more recent, but this is also spectacular of theirs: https://www.youtube.com/watch?v=7TV6BEwJEKI

Probably the "Television Rules The Nation" and "Around The World Mix". Goosebumps. Wasn't even a fan before the show either

Sam Cooke Live At The Harlem Square Club.
