It’s the Maconchy – essentially a concerto in four movements, each less than five minutes long – that makes the strongest immediate impression. What’s remarkable is the tautness of her invention: everything grows out of a rising figure comprising just two notes, from the stark, marmoreal opening through a perky, rhythmically tricksy second movement and a funereal third to the scampering finale. ... It might take repeated listens to the 1975 piece Eos to tune in to the idea that the music here traces the passage of the mythic personification of the sun across the sky; but its sonorities are immediately intriguing, overlapping and coalescing to make patches of texture that shift as if one is turning a kaleidoscope.  Erica Jeal
