The sound is difficult to pinpoint to a Bowie era, though the vocal approach and lyrics are closer to the late-70s works Station to Station, somewhat disconnected, political and even a bit paranoid. But the music works because Bowie has evolved while staying recognizable, and many of these tunes are catchy, energetic and worth returning to.
"The Loneliest Guy" is one of the saddest, most atmospheric songs Bowie ever wrote, not plastic soul but something more from the heart. "Looking for Water" is fine, "Days" has a bit of folk influence and "Try Some Buy Some" does justice to the George Harrison original. Lastly, "Fall Dog Bombs the Moon" has some of the best melodies and emotion of Bowie's career, although it's hard to decipher what the angry lyrics are about -- I'm guessing discrimination (the fall dog).
The title track is all noise (perhaps the Nine Inch Nails influence from 1995) and the final cut, "Bring Me The Disco King," is a moody Steely Dan-like lounge piece that goes on a bit too long. These two and "Looking for Water" are the most forgettable tracks here, but by no means are they bad songs.
Instead of reinventing himself or trying on new musical styles for the fun of it, Bowie seems to have settled into a groove with this one and Reality. If this is Bowie's final album to the world, it's a great way to close the story.
