is this the greatest live band of all time?

@dwiphefl1128 

I kind of want to hear a band that sounds better live than on their records

I have seen many bands that fall into that category as I believe most musicians/artists are energized by a live audience.  I heard two of your listed bands during the periods you list and both shows were outstanding:

• YES - 1976
• Genesis - Lamb Lies Down tour 

Jason and the Scorchers, circa 1984

Los Lobos, for about thirty-three years and counting

- I saw Pearl Jam open for U2 in Hawaii (2000's).  That was good.

- Pearl Jam in San Francisco was amazing (2000's).

- Rush in Toronto and Vegas. Rush is always great.

- Santana in Toronto (1990's) had me walking on air, so pumped up after that one.

- Recently saw a 100 year old Pete Townsend and Roger Daltrey in Vegas. It was shockingly great.

I saw The Who in 1975, Rush in 1976, but Santana not until the 1990's - all were great shows! Pearl Jam would have been a sweet show.  

Joe Cocker 1978 with 150 drunk sailors .he said it reminded him of playing pubs in England starting out. I was front row in a fold out chair. 3 hours of amazing rock and performance art. Plus not sure who his guitar player was but he was on point and in tune. 
Honorable mention Mothers Finest Citadel graduation concert. Where the plumbing never stood a chance.
