I agree that Marcus has a great jazz sensibility and some heavy knowledge of jazz history/theory. His playing with Miles was very jazz oriented, regardless of the fact that they were playing funk or pop tunes. Live especially, he'd do some great interactive playing, the same way an upright player would do when walking. Only Marcus was slapping. I think that he just chooses not to focus on that in his solo albums. He's emphasizing production, marketable songs, and air play. He kind of has to do that, he doesn't have the sell power to do whatever he wants and make money. I mean, he doesn't HAVE TO do that, he just wants to have a profitable career. With that said, Silver Rain is really bad, major disappointment. There's some incredible playing on it, and his musicality is undeniable. Its just instrumental pop garbage. It does have it's moments of funk strength, Frankenstien and Bruce Lee are pretty funky, listenable at the least. I certainly wouldn't call this a "jazz" album. Smooth Jazz maybe. It's just silly. I imagine, or I hope that he stretches this out live, and goes in more of the direction that he did with Miles. I haven't seen him live to support his solo material. Maybe I'll check him out if he comes around for this album. I just wish that he would take that chance to step out and record like that. That would be an album to hear.
