Conversation so far:
When did Rubinstein go on Anton Rubinstein's American tour?
At the behest of the Steinway & Sons piano company, Rubinstein toured the United States during the 1872-3 season.
What was the publics response to the tour?
The receipts and the success were invariably gratifying, but it was all so tedious that I began to despise myself and my art.
How did Rubinstein feel about America?
May Heaven preserve us from such slavery! Under these conditions there is no chance for art--one simply grows into an automaton.
Was their anything in particular that encouraged this sentiment?
May Heaven preserve us from such slavery! Under these conditions there is no chance for art--one simply grows into an automaton, performing mechanical work.

Question: Did he have any other revelations while touring America?
Self-contained rewrite: Did Anton Rubinstein have any other revelations while touring America, aside from one simply grows into an automaton in America?
