Originally conceived as a Royal Ballet-commissioned collaboration between composer Max Richter, choreographer Wayne McGregor and artist Julian Opie, Richter's gorgeous score to Infra is deservedly given life of its own in this album-length release. Expanded and extended from the original piece, Infra comprises music written for piano, electronics and string quintet, including the full performance score as well as material that has subsequently developed from the construction of the album ? more a continued reference to the ballet than as a "studio album" in the strictest sense. The composition resonates with Richter's characteristic musical voice ? majestic, involved textures; fluent and sweeping melodies; an enigmatic and inherently intellectual understanding of harmonic complexities that compels and mesmerizes. Richter plans to fit a US tour into his busy schedule this fall.
