Oni Press publishes Mondo Urbano

Powertrio, Overdose and Cabaret, comics about sex, drugs and rock'n roll, were originally self-pulished in Brazil, each in a different single color. Later, they published Encore, to tie things up, I think. I haven't read it yet, but it's been very well received by the public and critics.

You can see some of the art by yourselves here.

Now, it's been released in the US by Oni Press. Volume one gathers the four first issues. Hopefully, there'll be more coming.

The authors, Rafael Albuquerque, Mateus Santolouco and Eduardo Medeiros have worked for Marvel and DC, but they missed making their own comics, in their own country (I vaguely remember them saying something like that in an interview).
