Which band IS really America's Greatest (rock & roll band)?

I am old (70) and now have bad rearing from all the concerts I attended in the late 60s and early 70s, although I kept on going as I aged.

Three bands just blew me away in person and also via recorded music.

The Allman Bros. Band with Duane on the Live at the Fillmore tour in Pittsburgh just before he died still gives me chills as I remember how great they were.   They got their groove back with Warren Haynes and Derek Trucks later.  The basically invented the Southern Rock sound.

The Doors and Janis Joplin with Full Tilt Boogie we’re also amazing.  Sad we lost them so very young.  One final shout out to Canned Heat as they could also cook live.   The drummer is the only original member still alive, but he has kept the band going.

Hearing, not rearing, fruedian slip perhaps, LOL

The Doors are easily the best band from America for me, followed by the Velvets. 
Every album was different and brought something new.

50 years later the music remains timeless. Both bands seemed destined to self explode, but whilst they lasted that was the only predictable thing about them. 

I have an extensive vinyl collection. I got my first stereo system when I was in college. Money was tight but almost every weekend I purchased a new album to add to my collection.  I still have those albums and listen to them--they bring back the greatest memories. Some of my favs are Hendrix, Joplin, CCR, Aerosmith, Eagles, Allman Bros, Lynyrd Skynyrd, Zappa, The Stones, The Grateful Dead, Marvin Gaye, Boz Scaggs...I could just say I have a love for all things (music)  70s.

New to this thread but on the first page alone there were a few purely UK bands mentioned.

Makes you wonder...…

The best can be judged my many different variables.

I would say that there is no "best American rock band" What is boils down to is what an individual likes. I think a favorite American rock band thread would be more accurate.
