How is it that music that is so precise and obviously well organised can at the same time move with unforced, almost improvisational fluidity? And how can it be that atonal music sounds so natural and accessible? It's because De Raaff's music is nature itself; geometrically and architecturally stylised music it may be, but no different to the way a tree puts out its branches or how a leaf forms its veins. No different to the cosmologic nature of constellations, wave patterns on water, the pictorial architecture of a murmuration of starlings or a shoal of fish. In De Raaff's work calculation and spontaneity merge into a single, monumental but never massive whole.

Dutch pianist Ralph van Raat's collection of Arvo Pärt's piano music spans nearly 50 years of his career, from student pieces written in 1958 to a work from 2006. This would not be the right album for listeners looking primarily for Pärt's legendary austere simplicity, but it would be ideal for anyone already familiar with the composer looking for exposure to the broad stylistic and expressive range of which he is capable.

John Tavener’s piano works are less well known than his large orchestral, vocal and choral works, yet at times seem to mark his stylistic and spiritual development on a more personal level. Tavener’s first piano work, Palin, foreshadows his search for a spirituality beyond the sophisticated, technical manipulation of musical material. The loss of his cats inspired Tavener to write Mandoodles, depicting short scenes from the life of his cat Mandu, and the bell-like In Memory of Two Cats. Ypakoë, with passages in Greek or Middle Eastern style, is a contemplative meditation on the passion and resurrection of Christ. Pratiru¯pa, Sanskrit for “reflection”, is the composer’s largest work so far for piano solo. In the words of the composer, in this work “a series of self-reflecting harmonies, melodies and rhythms attempt to reflect the most beautiful, the Divine Presence which resides in every human being”.

This album of French piano rarities features seldom-heard and recently discovered works by composers who had an influence on Pierre Boulez, as well as the premiere recording of Boulez’s Prélude, Toccata et Scherzo. This large-scale early work looks back on virtuosic Romantic music, while at the same time exploring the new compositional styles that Boulez would subsequently embrace. Among the rarities is a posthumously discovered piano study by Debussy, a reconstructed birdsong work by Messiaen, and a tiny masterpiece by Ravel found in a notebook.
