Staying in Brazil and, thanks to etruck, Tachoblog can bring you your second video of the day – it is Wednesday after all!

At the Carnaval in Salvador De Bahia, Brazil, two million people party round the clock for five days straight.  Winding their way through the sea of celebrating dancers are Volvo trucks with specially built trailers carrying massive speakers, amplifiers, video screens and a stage for orchestras, singers and dancers. In Salvador they call them Trio Elétricos.  Volvo call them soundtrucks.
