Jimi Hendrix
Rory Gallagher
Led Zeppelin
Hendrix I never saw live. Isle of Wight would have been the only chance.
Rory Gallagher was the best gig I have even seen in my life. I still have a limited RG musical knowledge [Blueprint only on vinyl], and half the songs were unknown to me yet he blew me and everyone else away.
Led Zeppelin were good. Not astounding, just damn good. The least you'd expect from them really. Several others got close. Moody Blues, Yes, etc...
The Groundhogs were good and dirty. Ziggy era David Bowie. Simple Minds.
Bands who were crap: The Who - way under rehearsed and too loud. REM - just massively too loud Others - generally too loud. The Who were just **** though. Mainly rather stay at home and listen on vinyl though. At least they play the bloody music better.
