One in motorcycle gang knocked out by American musicians on the street (7)

I believe the answer is:

buskers

I'm a little stuck... Click here to teach me more about this clue!

'musicians on the street' is the definition.
The answer and definition can be both people as well as being plural nouns.
Perhaps they are linked in a way I don't understand?

'one in motorcycle gang knocked out by american' is the wordplay.
I cannot quite understand how this works, but
'american' could be 'us' (United States) and 'us' is located in the answer.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for buskers that I've seen before include "Street musicians" , "Street entertainer" , "Street entertainers" , "Street singers" , "They entertain in public places" .)
