The grandeur of simplicity Paul Hillier possesses a special rapport with the Estonian composer Arvo Part, 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 Part'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.
