I was on Easter Island for Easter week 2013. I went to performances of two dance troops -- Kari Kari and Te Raia. Te Raia is more pricey, but provided slightly better information, and both groups put on a good show. I think Te Raia is the better value, but if you just want a fun evening, Kari Kari is the better value. My impression is that the dancers enjoyed the show as much as the tourists. Musical instruments are not strictly traditional and the dance is more generically Polynesian than specifically Easter Island.
