Acting on a hunch, Danny located the dressing rooms. One by one he went through them. A robot had no need for privacy, but in the third room he found the piano robot. It was listening to music. Vaguely he was disturbed. Generally robots merely reproduced music; they didn't listen to it. Evidently the piano robot was different in ways he hadn't suspected. He'd have to find out about that, later.
He located a short length of metal bar and softly opened the door. The piano robot was still intently listening. A blow from behind knocked it sprawling. Instantly Danny followed with another blow to the side of the head. The robot jerked spasmodically.
Methodically he pounded the hands and arms into a pulpy mass. It wasn't flesh and it didn't look like it; through the synthetic skin covering wires and metal joints splayed as he struck savagely.
"Piano master." Danny straightened up. The human announcer was outside the door.
Danny looked around. There was no other exit save the way he had come in. He turned the music louder. The meta piano was not safe unless he could get out undetected. They would want to know the reasons for his attack on the piano robot and they had means to find out.
"Piano Master." The voice was louder, more insistent.
"Yes?" Danny muffled his voice, spoke through the music.
"The program will begin in ten minutes."
"I know. I'll be there."
"The music committee is waiting to accompany you. When will you be ready?"
