[Machine Translation] Since 1991, Michael NANASAKOV has been recording piano music that is not performed by ordinary pianists, mainly so-called "superb arrangements. While focusing on the Brandenburg Concerto, the gold standard of Bach's concertos, the album also includes three organ concertos that Bach arranged from concertos by his senior Italian musicians, and two harpsichord concertos that Bach himself arranged from his older works, in other words, a masterpiece collection that overlooks the connection between Bach and concertos, all in piano solo arrangements. In other words, the masterpieces that overlook the connection between Bach and his concertos are all recorded as arrangements for piano and solo piano.
