I listened to the pre-credits opening two minutes, and I'd bet a pint of warm beer that it's a mix of Dave Grusin and Quincy Jones. But since the imdb credits neither, I'll bet only a half pint.
Well, like I said: "no composer credited", so IMDb just reflects that. I can tell you that Tatro did a number of cues on episodes that reminded me of Grusin, so it wouldn't surprise me to find out it's by Tatro.
And thanks once again, thx99! I guess one of these days I'm going to have to start a "The Kick-Ass Music of KPM" thread where people list examples. Feel free (Anybody reading this) to steal my thread title and go ahead if I won't move fast enough for ya).
