A number of shows have been added to the Green Apple Music and Arts Festival. On April 19, the night before the Jammy Awards, Mickey Hart and Bill Kreutzmann will offer a rare Rhythm Devils performance at the Canal Room, officially kicking off the weekend’s festivities. On Friday, Hammond organ upstart Jonah Smith will move into, appropriately enough, at Pianos. Throughout the week of Green Apple, 79 year old jazz-legend Ron Carter will perform no less than 12 shows at the legendary Blue Note with his quartet, while Tea Leaf Green will make its debut at punk womb CBGB on April 22. A handful of additional performances will be added to Green Apple in the coming weeks.
