I would credit 'sucker mcs' as being the record that got me into hip hop music back in 1983. I used to break (thanks to break machine!) before I knew rap music existed. I remember seeing the video to 'The message' on top of the pops but I never thought much about it, (I do now o' course), but run dmc were the best hands down in my opinion. I bought streetsounds electro 4 just for 'sucker mcs' as US imports were impossible to get a hold of in the north of England. This, however is my fave record by them. I'm not sure but I think it's a promo only 12" single and I only bagged a copy about 18 months ago for a fiver off ebay. The B-side is listed as the instrumental but it's slightly longer than the vocal version and is more of a dub style affair.
