Hi, looking for an 80's breakdance movie, Beings with a teenager/teenagers painting grattiffi on some rooftop,

Later in the movie, dance crews perform on stage, there is on act where a crew have a large boombox prop in the background.

Thanks...

The only 80's break dance movies I remember (kinda) are Breakin' and Breakin' 2 .

Its not it but thanks :)
