Hi,
I listened to Rzewski's De Profundis for talking pianist , and its kind weird

, the sentences from Oscar Wilde messages and the whistling are understandable , but the part that the pianist act like an idiot or like an animal (4:30 , 8:10 , 23:15)

!! what is that , what that does (or should) mean ? I dont understand .Otherwise its a pleasant work

Thanks for the reply.
