This is the offical demo of the samba de enredo of the Unidos da Tijuca samba school. Unidos da Tijuca is the samba school that won the 2014 Rio Carnaval competition. The music played by a samba school for the Carnaval festival is called a samba de enredo. Unidos da Tijuca was playing this song as they paraded down the Sambódromo (Rio’s specially-built parade area). The song honors Ayrton Senna, the late Brazilian Formula One champion.

Here are two videos showing Unidos da Tijuca during the 2014 Rio Carnaval (the videos are quite long, so feel free to jump ahead; also, the videos can take a bit of time to load and then you might have to sit through a 30-second commercial before the actual video begins):
