• Sierra's ...Idilio..., a sensuous tribute to the Puerto Rican rain forest incorporating wordless chorus, reaffirmed one of the strongest compliments that can be paid to a composer today who chooses to work with traditional tools of melody, harmony, and rhythm: His music represents a unique voice, striking in its originality and bearing no traces of derivation or imitation.
