definitely 5, 45, 11, 47, 7, 30. 27 has very obviously modern produced drums but it's such a cool first wave sounding record otherwise, and you don't have 19 rated so definitely check that out at some point
89 and 64 arent black metal raw sounding but they are still great examples of early 80s speed. 64 is the coolest album ever really
#2 here is chock full of blasties but for some reason it doesnt bug me. helps that there are some awesome dbeat sequences throughout to break up the blast-monotony
