Well, at first I thought it lacked a lot, felt like a return to his late 80's pop sensibilities, which after the genius of his 90's work, like Outside, seemed like a sucker punch.
Still, I'm nothing if not an ardent Bowie fan, and repeated listneing does deliver an appreciation for the musicianship rampant throughout the work. Lovely sounds, if not songs. His own vocal performance is strong, the timbre of his voice takes on delicate nuances as he's aging. He can tremble and flutter in a manner that feels authentic now, whereas pulling that same hat trick before sounded...pretentious, even from him.
Reality is worth listening to - it's easily enough downloaded, but be prepared for having to work at liking it.
