It is an utterly amazing collection, although not the era I am the most familiar with. However, let me add a few as I love your initiative and went through them all and skimmed the ones below to get a sense of the quality.
Billy Bragg:

Not the cleanest vocals on either of the recordings, but the former is overall higher quality from what I could tell.
Boogie Down Productions:

Excellent recording and great live act, just a pity that it is rather short.
Mojo Nixon:

Another great live act and recording. I am sure Mojo would very much approve of this being shared as well.
