The grandeur of simplicity Paul Hillier possesses a special rapport with the Estonian composer Arvo P�rt, with whom he has worked for many years, patiently exploring the different facets of his music. This boxed set assembles this major recording legacy (1996-2012) in it's entirety for the first time. It represents a significant milestone in our understanding of P�rt's unique musical universe, characterised by a purity and inwardness inherited from the great tradition of Gregorian chant. A pioneer of 'historically informed' performance, Philippe Herreweghe recorded a extensive selection of Bach's finest cantatas with harmonia mundi - versions now regarded as milestones in the works' discography. This boxed set provides an opportunity to rediscover that legacy in it's entirety: twenty years (1987-2007) in the service of one of the Kantor's richest and most indispensable bodies of work.
