Here's the themes (Enredos) of each of the 12 samba schools parading in the top group of Rio carnival 2011, on the Sunday and Monday nights of carnaval. The Carnavalesco is the overall designer of the parade. Each school parades with around 4000 costumed participants and 8 large floats. The parade is divided into sections with costumes and floats illustrating aspects of the theme. Each school has its own song (samba enredo) written specially to explore the school's theme.
Imperatriz’ samba enredo has been voted the most popular of the Grupo Especial songs for Rio Carnival by a specially selected panel of judges in O Dia, the Rio de Janeiro newspaper. I agree; nice melody, good lyrics and, crucially, easy to sing.
Imperatriz’s theme for carnival 2010 is ‘Brazil of all the gods', and you can see a preview of their costumes for carnival 2010 here. Imperatriz’s carnavalesco (artistic designer) is Max Lopez. The official Grupo Especial CD is released on 7th December; you can buy it here.
