Lucky you got to see Chick, and I've seen videos of him and Gary Burton. What a great duo!
Something that amazed me about Chick Corea was his ability to go so seamlessly into such different musical directions. Weather it was acoustic piano, Rhodes, or synth, straight ahead jazz, Latin jazz, funk/rock fusion it always sounded like Chick. Although his music was complex, it always sounded joyful and has soul.
I had seen him recently doing online workshops, and thought how great and fit he looked for some close to 80. So sad...
