LL COOL J
A week or so I posted some old school hip hop, so I thought I'd post some more.
In 1987, I was watching Saturday Night Live. Sean Penn (who at the time was married to Madonna) was the host and did a bunch of pretty funny skits. Then, about 40 minutes in, this came on. LL Cool J wasn't the first rap act to appear on SNL, that was actually the Funky 4+1 More in 1981. But when you look at the audience, it was obvious they hadn't seen much of this kind of thing.
Despite the tepid response, LL still managed to blow the roof off 30 Rock that night. The audio is crap on this clip, but it's still exciting to see when hip hop was still new and exciting and desperate to prove they deserved the respect afforded to rock artists.
