Soundgarden Post Series Of Teaser Images

Soundgarden appear to be teasing something, posting the following image which features the text: “words unspoken breed no restraint.” There’s also some other teases popping up around their social media, one of which can be found below. You may recall that guitarist Kim Thayil previously mentioned a proper b-sides and rarities release was in the works. No official word yet on whether or not that is what these images are teasing.
