(Re-structuring my idea here)
Lately with MP I've been feeling that his music is being made out of pure inertia, and ends up sounding just repetitive.
I agree that both he and NM make such tons of music that it's difficult to come up with something new all the time, however, this isn't something new, and not exclusive to Neal Morse, it kind of happened too in Sons of Apollo.
In pretty much every Neal Morse project he kind of sounds the same, like he just sits and plays.
Sure, that's his style, but after so many hours worth of music and so many CD's it kind of starts feeling heavily repetitive, like, seriously, if you isolated MP's drum parts from several songs and scrambled them, I highly doubt I'd be able to distinguish any of the songs.
