When we were in NYC last summer, some guys entered the subway train (we accidentally reached Harlem

) who had a Ghetto blaster and started to Break dance like crazy while the train was running. One guy lifted himself on one hand SLOWLY up and down....totally amazing, totally muscles.
Didn't dare to video them...but gave them a buck when they went around with their hat...enjoyed the show and I love those things about NYC...
Still I'll avoid the too obvious rock-steady crew for now

Another new things in the 80s was rap. I actually liked it then. First one I ever heard was Kurtis Blow with Christmas Rappin':
