Autograph letter signed from Pyotr Il'yich Tchaikovsky to Adolph Brodsky

Tchaikovsky has not written earlier because he has been busy with the ballet score. He apologises for the muddle: there will be 3 evenings not 4, but the takings will be magnificent. Of the pianists, 2 are especially influential and will draw an audience; and they feel very honoured to play with the quartet. They have done well to be rid of Erdmannsdorfer and his wife is quite insufferable. Tchaikovsky will write soon with details of what the pianists have chosen to play with the quartet. He requests Brodsky to choose incidental pieces without orchestra [for the concert on 28 October]. Dated 15 Sep 1889.
