Roll & Rock!

Traveling musicians, rejoice! With keys just an eighth of an inch thick, the 2-lb., 61-key Hand Roll Piano rolls up like a blanket and spreads out to about 3 ft. in length. Incorporating technology used in remote-control buttons and touch panels, the silicone-rubber keyboard, which has a built-in speaker, can be played for up to 15 hours on four AA batteries. But it's no lightweight. The Hand Roll comes with a set of 128 tones (from acoustic piano to bird tweet), 100 rhythms, 20 prerecorded demo songs and a speaker jack, and it connects to a computer.
