I'd skip Bomb/360 U2 for any of these...
70's ZZ Top
Dylan's Rolling Thunder Revue & the 'Judas' gig.
Prince any time apart from the mid to late 90's
Neil Young & Crazy Horse Tonight's The Night or Live Rust
60's James Brown
Stones 68 - 72
Elvis any time
Beatles Hamburg (before the feckin screaming)
Jerry Lee Lewis early 60's
I'd take Bomb-era U2 over all other tours U2 has ever done. Peformance-wise, they were at their absolute best on that tour.
Back on topic:
Duke Ellington Orchestra, late '40s/early '50s ( my mom saw them a few times back then)
Miles Davis Quintet, early 1960s
Bob Wills & the Texas Playboys, 1945-46 (when Junior Barnard was inventing rock lead guitar)
Yes, Going For The One tour
...and maybe Frank Zappa & the Mothers, Geneva, Switzerland, December 1971.
