The World Cup is an excuse to enjoy a lot of things, but as any ESPN commercial will show you, it is impossible to separate any invocation of Brazil from its music. In my case, it's Banda Black Rio, best thought of as the pre-J.T. Kool and the Gang of Brazilian funk.
Oh, it's also the perfect time to read Supriya Nair on the dream-time of the World Cup. No reason you can't do both at once.
