- 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.
The fortress also shall cease from Ephraim, and the kingdom from Damascus, and the remnant of Syria: they shall be as the glory of the children of Israel, saith the Lord of hosts.
Isaiah 17:3 KJV
