The Russian pianist Denis Kozhukhin (Nizhny Novgorod, 1986) is in Barcelona to perform Rachmaninov’s four piano concertos with the OBC at L’Auditori this weekend and the following one. These concertos are considered to be among the summits of piano literature, as well as some of the most difficult that a performer can tackle. As if that were not enough, he will complete his visit with a chamber concert alongside the violinist Janine Jansen.
