help about that avantgardistic artist....

[effi_deep]

i've found a record of a brasilian artist called rodolfo caesar. the record is called "a arte dos sons". it's pretty much some avantgardistic synthesizer only stuff.
tried to find something on google but i didn't.
i don't know, but seems to be a pretty rare thing. looks like a private press too. no label on it.
any help?
i have a spare if anyone is into that kind of music and can give me some information....
