The work's title, borrowed from Schiller, represents the two opposing modes of artistic creativity: Naïve--spontaneous, unconscious of any preexisting work; and Sentimental--fully aware of, and thus impeded by, what already has been created. Whether Adams has succeeded in expressing this dichotomy will be up to the listener to decide, but on purely musical terms he's come up with an affecting and quite involving composition.

The strumming guitar and harp at the opening of the first movement creates an idyllic atmosphere that soon becomes troubled as the music gets progressively darker and builds up the first of three massive crescendos (separated by brief interludes). The tutti passages are indeed ferocious, making this some of the more jarring music Adams has ever composed. The guitar returns for the elegiac and tuneful second movement, "Mother of the Man", which like Harmonielehre has an agitated middle section based on tortuously ascending chromatic scales. The finale "Chain to the Rhythm" lives up to its title by employing an insistent rhythmic pulse throughout (as does the first movement). Again there is a long crescendo, this time building to a crushing final climax that leaves the horns blaring into empty space.

Esa-Pekka Salonen, who premiered the work with the Los Angeles Philharmonic, here leads the orchestra in a powerful yet highly polished performance that emphasizes Adams' glittering orchestration. If a concert broadcast with Adams leading the Chicago Symphony made a greater impression, it's no doubt due to that orchestra's more aggressive brass playing (the brass play a major role in both outer movements). No matter; anyone coming to this music for the first time via this recording is in for an experience that will provoke much thought and feeling, especially if they turn up the volume to get the full impact of Nonesuch's vividly realistic engineering. Naïve and Sentimental Music is definitely not a crowd pleaser in the manner of Adams' The Chairman Dances, but it's an important and stimulating work nonetheless.
