Query: "Flowing Like Oil..."

Mozart, addressing future performers of his Piano Concertos is quoted as saying "...just make it flow like oil!" Schumann, like Mozart, takes a predominantly lyrical approach in this concerto and the music portays itself as one inspired stream of genius. It is. And in the hands of Richter, this stream soon becomes a raging rapid of emotion. Flows like oil? Yes!
