This a cappella collection of pieces for mixed choir by Eric Whitacre is the first available printed music compilation of its kind for the composer. The book includes pieces of varying difficulty, wide-raning in theme, from the iconic Sleep and Water Night to the quietly angelic Lux Aurumque (Light and Gold) and the recent Nox Aurumque (Night and Gold). A Boy and a Girl and This Marriage are both wonderfully tener pieces and the inclusion of the early Go, Lovely Rose marks the beginning of a journey thorugh Whitacre's choral output from this first success to the present day.
