Somm Recordings and former BBC Young Musician Competition prize- winner Cordelia Williams present two sublime voices together for the first time on album in a poetic and probing coupling of the solo piano music of JS Bach - musical laureate of 17th-century Protestantism - and Arvo P�rt, principal voice of contemporary Holy Minimalism. Although a quarter of a millennia separates their births, both share a conviction that faith in God, as Williams notes in her introductory essay, "is the foundation of the creation of music." This pioneering coupling of the two composers reveals a surprising latticework of connections in their constant, shared striving for economy and essence. P�rt's signature chiming 'tintinnabuli' style is beautifully evoked in three pieces designed to console and comfort their dedicatees: the tolling, melancholic profundity of F�r Alina; the quietly majestic and moving F�r Anna Maria and the limpid, liquid invention of Variationen zur Gesundung von Arinuschka. Composed for his 10-year-old son, Wilhelm Friedemann (himself later a composer of distinction), Bach's twin sets of 15 Two-part Inventions (BWV 772-86) and 15 Three-part Sinfonias (BWV 787-801) are much more than mere pedagogic primers. Williams finds in them a richness of technical design far beyond their apparent simplicity. Here, Williams reverts to Bach's original ordering of the pieces to chart a subtly revealing way through music as intimate as it is illuminating.
