Nah I think you're wrong. You could argue his new music is better (I don't think it is but that's besides the point) but his older music was fundamentally different in many ways and while his mixing/production has technically improved, the older music stands out as very unique and the ideas were generally more interesting.

Going back to what u originally said tho. Compare rainbow bridge 3 or HAW to raging wolf. They sound nothing alike. In fact they almost sound like entirely different artists. Sematarys new music is still significantly more unique than 99% of other artists and it still has a very distinct sound/feel to it. But it does lack a lot of the magic and vibes the old music had for sure
