Here are two samples of  The Days of Wine and Roses where Bob plays on a Steinway Grand Piano and then on  his Keyboards, so you can hear  and compare for yourself.

Bob's  Keyboard sound uses the same exact  Grand Piano Sound, and adds Bass and Rhythm so you get the sound of a 3 -4 piece group.  In addition, we can add the sounds of Vibes, Electric Pianos, Strings, and dozens of other instruments to add variety to the music.  A  high quality stereo sound system is used for complete and total control of the sound  at any volume the customer requests. Savings over using a  rental piano would be around 75%, by using Bob's keyboards.
