about your compression question: hmm i don't know if there are artist which would really match your criteria... i like flying lotus out loud myself though, so i guess it's all about taste ahah.
but, overcompressed artists that i think keep weight:

there are a fair number of overcompressed wonky artists nowadays:
slugabed:

loops haunt:

etc.
personally, i think they manage to keep their power despite the over compression...
by the way if you want some lively wonky:
mike slott - gardening
oh and this too, though in another meaning of lively ahah:
hudson mohawke - joy fantastic (best video ever, too)
