I think of true grunge as lo-fi or at least not overly produced. That to me is what distinguished early Nirvana (Bleach) as grunge and later Nirvana as rock, and what distinguished Soundgarden as rock. I used to think of Beat Happening as grunge, too. Now people lump them into twee pop, which greatly irks me since twee pop wasn't even a term when the band was around.
