The sentence is unclear because of the disagreement between the subject and the verb. "Tommy the Clown" is a singular noun. The sentence then states that "the Hip Hop Clowns" is another name to refer to the same person, however, this is written in plural form. The verb "travel" is written in a plural form, which does not match the number of the subject "Tommy the Clown." The right way to write this sentence would be:
"Tommy the Clown or the Hip Hop Clown travels the world performing for diverse audiences."
