My last name is very unique and I can no longer have that associated with myself as an entertainer.
Why not? When I tell my clients and professional colleagues I play in a band, I get nothing but positive comments and it's had no negative consequences on my professional life at all. As long as your social media posts as an entertainer are generally "clean," you shouldn't have anything to worry about IMO. I think people generally understand that someone may have very different interests outside of their careers. The Wall Street Journal recently profiled the CEO of Sprint, who does a weekly online video cooking show.
