All musicians, particularly drummers, tuba players and pianists, envy singers. While all the musos in the former list are required to invest in an expensive musical instrument and buy a large van for carrying it around, only to end up with back strain from hoisting it about, singers just waltz up to a microphone and they're off. Well, pianists rejoice, because this is your equaliser: the Roll Up Piano. The flexible rubber keys allow the keyboard to be rolled up to fit snugly next to the control strip, which also includes a built-in speaker and volume control, and can make at least 100 different sounds. Forget the blues man with a guitar strung across his back, take the Roll Up Piano on the road and rock them with Rachmaninov.
