Hi Spalding
Used to be very popular in the 80s & 90s with most organists/keyboard players doing a keyboard drum solo, (I still think Max Takano on the HX1 was the best then) and as far as I am aware, Mark Whale is the only one these days that does the occasional drum solo on the keyboard.
I have always liked a drum solo (Real or on a Keyboard) and enjoy listing to them, Thanks for posting.
