Singapore's entertainment culture is officially supported and internationally ambitious. The Esplanade — Theatres on the Bay, a purpose-built performing arts centre on the Marina Bay waterfront, hosts a full season of international and local theatre, opera, dance, and music with a programming ambition that has made it a genuine cultural institution. The Singapore Symphony Orchestra, the Singapore Repertory Theatre, and the Wild Rice theatre company form a performing arts ecosystem of real quality. ZoukOut — held annually on Sentosa Island — is one of Asia's largest outdoor electronic music festivals. The Singapore Night Festival, the Singapore International Film Festival, and the Formula 1 Singapore Grand Prix night race (the only night race on the Formula 1 calendar) add major event entertainment to a year-round calendar.
