- Piano Concerto No. 1 (Tchaikovsky) (Wikipedia)
The Piano Concerto No. 1 in B♭ minor, Op. 23, was composed by Pyotr Ilyich Tchaikovsky between November 1874 and February 1875. It was revised in 1879 and in 1888. It was first performed on October 25, 1875, in Boston by Hans von Bülow after Tchaikovsky’s desired pianist, Nikolai Rubinstein, criticised the piece. Rubinstein later withdrew his criticism and became a fervent champion of the work. It is one of the most popular of Tchaikovsky’s compositions and among the best known of all piano concerti.

Designed by architect Bruce Graham and engineer Fazlur Rahman Khan of Skidmore, Owings & Merrill (SOM), it opened in 1973 as the world’s tallest building, a title that it held for nearly 25 years. It is the third-tallest building in the Western Hemisphere, as well as the 23rd-tallest in the world. Each year, more than 1.7 million people visit the Skydeck observation deck, the highest in the United States, making it one of Chicago’s most popular tourist destinations.
