Mine has to be Bruce Springsteen and the E-street band. Of course they are straight outta Jersey.
I think you first have to ask yourself what's the criteria based on ?
Impact the had on music
Longevity as a band or solo artist
ability to maintain the original line up
to many possibilties
The Allmans are my favorite band , but the rest are my favorite bands/musicians that have had a great impact on the world of music with their music.
