Does this 90s Seattle band description ring any bells?

I was messaging a contact in Victoria, British Columbia in Canada, and to cut a long story short, he says that when he went to see the Proclaimers at a theatre in Victoria, in about August 1994, that a grunge band who said they were from Seattle showed up as the support act, and played for about 20 minutes. He says the he can't for the life of him remember what the band's name was.
-
The crucial details that he remembers are that they looked to be in their early/mid 20s, sounded really heavy "punk metal grunge", were dressed in all-black, black jeans, black Ts, were all guys, and that there were 4 or 5 individuals in the band in total (he thinks 5 is most likely but he's not 100% on that).
-
If anyone has an idea, even if its a longshot, of which band this might be - my best guess is Willard, but that is based purely on the best match for limited information - that would be awesome because he's really keen to know which band this was.

Besides the big four I would guess My Sister's Machine, Gruntruck, TAD, or Coffin Break.

Yah, TAD and MSM seem pretty plausible. I don't think it'd be one of the big four, because they were already pretty famous by this time, and are unlikely to be supporting an only moderately successful band - probably more likely to be someone either Mudhoney level or lower. I think Gruntruck or Coffin Break broke up around that time so...

Since MSM, TAD and Willard seem most likely, I will send this guys some of their tracks, and see if he recognizes them.
