There were too many great eras of music to pick just one. That aint fair. Over the years I have heard many of my favorite artists play live and I couldn't pick any one of them. I have seen Benny Goodman , Stephane Grappelli, B.B.King, Frank Zappa, Jeff Beck, Return To Forever, George Benson and so many more brilliant artists play live. Such a wide variety of musical styles from so many eras and I love them all.
