Were pre Grunge bands just a little before or the same time as
Nirvana. None had anywhere near the same success.
The year punk broke I think was a doc movie about
Grunge and Nirvana breaking into mainstream music
in 1991 with their album Nevermind, not their first by the way.
The year punk really broke was 1976 with the Ramones first album.
Just my opinion.

Was really the first Grunge band though 1985
I myself never considered Grunge to be Punk Rock.
There were quite a few others as well.
Of all of the more minor bands Mudhoney was probably the best.
All be it none were very tuneful though.
