rock n roll

It was good to see how there was less racism in Cadillac Records than in the years prior. Rock n roll of this age brought both younger blacks and whites together. I don't remember specific names in the movie, but it was nice to see how the white guy (owner of the bar) stuck up for his artist (black guy) when his face was getting pounded into the car by a cop. It showed a new level of respect that white people were growing for blacks, although there was a good deal of racism when the cop cursed the "n" word at the musician. Did this new sense of respect in the music industry carry over to the general society at all? If so, how much of an impact did it have?
