"KitKat Club" probably refers to the KitKat Club in San Francisco, a known live performance venue that hosts a variety of acts, including avant-garde, cabaret, and burlesque. The word "Avantgarde" is likely part of the club's identity, emphasizing experimental or innovative performances. "Extreme Scat e New" is a bit confusing. "Scat" could relate to scat music singing, which is a form of vocal improvisation. "E New" might be a typo for "New E" or "e.New," but I'm not sure. It could be an event name, a performance, or maybe an artist. Given the context, I'll need to verify if there's an actual event or artist called "Extreme Scat e New" associated with the KitKat Club.
