Pianists are long-time friends of the caffeinated beverage. Improvisational pianist Gregg Kallor's video Espresso Nirvana looks at what happens when you drink too much of the stuff. Best of luck to Gregg on the release of his new album A Single Noon, scheduled for early April. Gregg's bio lists him as a composer well-versed both in classical and jazz traditions, and (classical musicians take note!) I like the way he weaves the concept of the video into what might otherwise seem a dense composition.
