I lived in NOLA for 4 years - '84 - '88. Saw Billie Joel perform in a small local bar. Also saw Ray Charles perform in a very small venue - 25 bistro tables -= 50 people. My table was 10' from his piano. After his performance he walked the floor and shook hands with everyone in the audience.
I did not wash my hands for a week!! Another small venue - the great Louis Armstrong. Love Tina Turner. She is no young chick but can still rock a stage. Her athleticism amazes me. Sad that she suffered so much at the hands of that animal she was married to. Willie Nelson at the Saenger Theater. Great performance. Numerous, amazing artist at Jazz Fest.
IDK if you are familiar with Aaron Neville. I have seen him perform several times both in NOLA and Lafayette. He is a big, bad ass biker looking dude with the voice of an angel.
My taste in music is very eclectic. I forgot to mention Ella Fitzgerald - the Queen of Scat. Mahailia Jackson - the Queen of Gospel. Unfortunately so many of the recordings of great artist are very poor quality.
