Keone and Mari Madrid are hardly strangers to the spotlight. Together, the powerhouse partners have performed in a Justin Bieber music video and on "The Ellen DeGeneres Show," and have choreographed for "So You Think You Can Dance." With around 250,000 subscribers, you could say Keone and Mari are "YouTube famous," but, thanks in part to a successful stint on NBC's "World of Dance" last year, they've become much more than that. Case in point: They're currently co-creating, choreographing and starring in their first full-length production, Beyond Babel. The immersive show will debut in San Diego this month; Keone and Mari hope to eventually take it on tour.
