I think Mudhoney was probably one of my favorites from that era/location (even though they were pretty much just your typical garage rock band, but they got labeled "grunge").
Does anyone have any "obscure" bands worth mentioning that got that "grunge" label (obscure meaning not Nirvana, Soundgarden, Melvins, Pearljam, Alice In Chains, etc. or any other well-known 90's Seattle bands; they were all pretty good, but they are household names, whereas I'm looking for bands a little more under the radar.)
