So by 'skronk' we're referring to to those sounds extending beyond the base notes played? That feedback, over modulated, distortion etc. etc.
Wouldn't that make 'skronk' synonymous with noise? Based on your Mote example I'd guess this was the case. But why mention those five particular bands than any number of straight up noise bands? All of those bands are well, fairly conventional by relative standards, especially Dinosaur (no digs against Dinosaur, they're my favorite). Dinosaur Jr. is really just a straight up rock band when you get down to it that happens to employ high amounts of volume and distortion.
So, in my understanding skronk is the highlighted noise that is an extension to the core rock and roll dynamics employed by band of your choice.
Techno rules.
Boredoms' Circle and Rodan's Toothfairy Retribution Manifesto come the closest to the music I hear in my head. Also anything where drums thunder.
