Here's the concept: The structure of most pop songs consists of only two parts, the verse and the chorus. Since the verse and chorus usually repeat three times in a three-minute song, a pop tune really only consists of one minute of music. Cut out the repetition and you can, therefore, fit 40 pop songs onto a 40-minute record. And that's exactly what the Residents have done on The Commercial Album, the title of which comes from the band's deduction that since pop songs only consist of one minute of music and most advertisements are about a minute long also, ad jingles are "therefore the music of America." Got it? Whatever the concept behind it, this album is not only weird in that special way that only Residents albums are, but it's also surprisingly musically satisfying. A few of its 40 tracks ("Secrets" and "The Simple Song," for example) feel like throwaways, but most of them are surprisingly well organized and complete. The instrumental "Japanese Watercolor" is particularly impressive, as are the songs "Picnic Boy" and "Troubled Man." This album would make a great introduction to the Residents for anyone who hasn't yet been exposed to the band's unique brand of whimsy.
