Top rock is a preamble to a breakdancing set.
The song break is going to hit. You get a rush and it’s your top rock that warns the crowd as you skillfully open up a hole. The elation you feel, body tightening and your senses narrowing as you set to your task.
First the top rock, then the groundwork, followed up by a power move. There are freezes, transitions, tricks and flips sprinkled throughout a routine.Thats what a break dancer does.
