The thunder and delicacy which characterises the best harpsichord music when played on that instrument also characterises this latest recording from young London-based pianist Pavel Kolesnikov. That, and originality. Of the pianist, whose previous recordings featuring the solo piano music of Tchaikovsky and Chopin, are just the right side of idiosyncratic. And of the French Baroque composer Louis Couperin (c.1626-1661), uncle of the more famous François Couperin (“Le Grande”) and composer of some of the most beautiful and influential works for harpsichord.
