I've been on and off working on his LH patterns. I can get the patterns but then put the RH to it and sing is the next step.
Bill....it's interesting that we're not only both piano pro's but that we think alike. I'm still working on that JLL left hand technique. Like you, I find that now that I got the LH working, I've got to put both hands together, and then sing on top of it all. But it's coming along for me.
Yes, you can play the finest arranger keyboard in the world, but it will sound nowhere near like a human being pounding out rock 'n roll on an acoustic piano. The thickness of those bass notes really get you stomping your feet.
I'll never forget years ago. I was at a piano performance. The pianist played "All The Things You Are" straight the first time. Second time she did "walking bass." I almost fell off my chair at the difference it made. Sounded like a whole trio. And that's just "walking bass." When you get to JLL's level, (IF you get to JLL level), well, then you've arrived. That's when you pick and choose where you want to play.
