102 key piano

There is a grand piano out made by Stuart & Sons that has 102 keys rather than the standard 88. It tends to focus more on bass, and does have a different sound than a normal grand, be it a baby grand to a concert grand. Some composers have already begun composing music to utilize the use of a larger, more grand size keyboard. They are selling for about $300,000. Here's a link to their site and it being performed on.
