Because it's winter time in Hawaii and because it's the time that I appreciate my geographic disposition the most, now is my favorite time to play 'Summertime'.
It's fun to put a bit of a Dorian spin on things with blues and bebop lines mixed in. 'Summertime' is probably the most overplayed standard out there. But experiencing and amazing stage performance of Porgy & Bess a few years ago really made me love the piece again.
The Gershwins were an amazing team!
