Equally as much progg as punk can be found in the sound of GBG(short for Goteborg) Sound. The rock n roll riffs that became the trade mark of the whole late 70s punk scene in Gothenburg was maybe used the most by these nice looking lads.
To me Pappas pojkar is their best song tightly followed by Bjorn Borg(the first record posted here). Just listen to the spitting break at 1:31 into the song and you know that they’re serious in their hate against brats supported by their rich dads. If they where around today I guess something like this would’ve been a great inspiration.
