Departing from the Beach Boys' surf-music roots, "Pet Sounds" was an emotive and carefully planned recording that attempted to present an album as a unified work and not merely a collection of singles. The album is notable for Brian Wilson's lead vocals* and the harmonizing support from the other band members. Equally compelling are the melodies and the arrangements, the latter featuring, among other instruments, horns, strings, theremin, accordion and a glockenspiel. The album has proven to be the most complete statement of Wilson's musical and lyrical aesthetic.
