“Four grand pianos are four times better than one”: we are publishing several media reports from a rehearsal of Alexander Tchaikovsky's Piano Concerto. 

The world premiere of the concerto will take place on 13th June at the opening of the _Grand Piano Competition_, with the participation of virtuosos of the Russian stage — Denis Matsuev, to whom the composition is dedicated, and also laureates of previous years' competitions: Petr Akulov, Ivan Bessonov and Sergey Davydchenko. Alexander Sladkovsky will be at the conductor's desk with the Svetlanov Symphony Orchestra of Russia.

What is the idea behind the composition, how the pianists synchronise their parts with each other and why Denis Matsuev records wrong notes on a large abacus... find that out in media reports from the concert rehearsal.
