It is January, and squeezed away upstairs in their favorite sushi restaurant in downtown Sao Paulo are the six members of CSS plus a stray boyfriend. (Turns out he belongs to producer-cum-drummer Adriano Cintra, the only fella in the group.) After 18 months touring the world, they are back home in Brazil to record their second album, which at this moment might end up being called "Donkey" or might end up being called "Hunk of Sh*t." Shortly hereafter, once the album's finished and it's summer festival season in Europe and North America, the band will split this sprawling megalopolis for good. But this evening, as the rain slams down in the subtropical streets outside, the sake is flowing.
