Dr. Dre’s mixing. He did not and does not master albumsContender for GOAT album. This album sounds so crisp. Dre’s mastering had reached its peak. Sonically I don’t think this album can be touched. Plus Dre brought that whole futuristic g funk sound that took over the early 2000s. So glad I own this on vinyl. I can write a book about this album but I’ll just leave it at that.
