First off, the following albums were released a while ago and are still unavailable in Brazil:
Black Label Society - Catacombs of the Black Vatican
Crowbar - Symmetry In Black
There is also a Brazilian metal band called Gloria, which is being mixed with a international singer under the same name.
Also, a Brazilian rock singer called Rodolfo, which recorded the albums Estreito and Rodox, is being mixed with another singer under the name of Rodolfo as well.
Also, it would be nice to have the album To The Pain by Nonpoint available in Brazil as well.
