Is there a difference between morphing and evolving? I do hear elements of the former sticking around and showing up in the latter, to then further evolve.
Some organizational things had changed in some pretty basic ways and they stuck around.
And I forget where Broken Beat/Drum & Bass (all the labels...) falls into the chronology, but that was some replacement toolbox stuff as well.
Beats, changes, melodies, TEMPOS!, nothing is as it was, and one person, place, or thing didn't do it alone or at once!
IMO, this micro wacko subsubsubsub genre labeling is missing the bigger point that a significant portion of the collective reality-perception/dance mojo (instinctual/ behavioral, not social) has changed. The people have changed. The shapes and colors have changed. Accents have changed
Life has changed. The resistance is strong, but...you can't stop running water.
