Question Is the 'Feel Yourself Russian' Folkloric Show in St. Petersburg Worth It?

We will be in St. Petersburg during the first week in June via a cruise ship for 2 days. I came across the 'Feel Yourself Russian' folkloric show and it seems interesting, but I'm wondering if it's worth fitting into our tight schedule. Has anyone attended this show? How was the experience, and would you recommend it for someone looking to get a taste of Russian culture in a short time? Also, any tips on booking or what to expect would be helpful.
