Disagree. A lot of random styles thrown around on the solo albums, albeit with a familiar folky theme running through.

You Don't Know Youre Born

I see your point Dusty and indeed you are right in the fact he has going through different styles in his solo work, but in term of melodies or songs keys (almost all Tracker songs are in C) I find that his solo work has more the "same rengaine" feeling that the DS stuff. Maybe it's just an impression ?
the 2 firsts albums have the same guitar tone on all tracks, and are all in the same style, with pentatonic blues scales, BUT by listening I find them with far more variations than say KTGC or Tracker which feels to be more "static" more "linear", can't find the right word to express what I mean.
His solo stuff is more "pépère" like we say in french, more "safe zone", while on the DS stuff he seemed to take more risks.
I think it's hard to get some "surprises " on a recent Mk album, we know almost all type songs we will get before the release (celtic, ballads, H. Marvin stuff, maybe some classic blues and that's it) while I bet that fans who discovered MM or LOG were quite "surprised" in comparison to what they had heard before. I hear more musical "evolution" between communique and BIA for example, than between TRD and Tracker, but again it's just my opinion, and my hearing impression. Of course, I don't pretend to say the truth
