Though Fear of Music is musically distinct from its predecessors, it's mostly because of the use of minor keys that give the music a more ominous sound. Previously, David Byrne's offbeat observations had been set off by an overtly humorous tone; on Fear of Music, he is still odd, but no longer so funny. At the same time, however, the music has become even more compelling. Worked up from jams (though Byrne received sole songwriter's credit), the music is becoming denser and more driving, notably on the album's standout track, "Life During Wartime," with lyrics that match the music's power. "This ain't no party," declares Byrne, "this ain't no disco, this ain't no fooling around." The other key song, "Heaven," extends the dismissal Byrne had expressed for the U.S. in "The Big Country" to paradise itself: "Heaven is a place where nothing ever happens." It's also the album's most melodic song. Those are the highlights. What keeps Fear of Music from being as impressive an album as Talking Heads' first two is that much of it seems to repeat those earlier efforts, while the few newer elements seem so risky and exciting. It's an uneven, transitional album, though its better songs are as good as any Talking Heads ever did.
