“I shall not alter a single note,” I answered, “I shall publish the work exactly as it is!”
So said Tchaikovsky after receiving blistering criticism from pianist Nikolai Rubinstein after hearing Tchaikovsky’s first piano concerto a few days after the composition was completed.  Rubinstein, who is known for debuting Balakirev’s insanely difficult Islamey,  deemed the concerto “unplayable” and “vulgar.”
It would appear Tchaikovsky was vindicated. The first piano concerto met with great audience acclaim at its debut in Boston, and has become one of Tchaikovsky’s most popular works. Rubinstein later came around, both playing and conducting the work he once vilified.
Tonight at 8PM EST (GMT -5) the Detroit Symphony Orchestra will present a free live concert webcast, which will include Tchaikovsky’s concerto. The concert will feature conductor Dalia Stasevska and pianist Simon Trpčeski. You can see the webcast at dso.org/live or on Facebook Live. Here’s the program:
