Techno and house music scene in Rio

hey there,
i ll be in rio for 3 weeks for my first time , and i am having difficulty finding out where to go for good techno music nights. i usually use the website
residentadvisor.net for when im going out in dublin, london or berlin. but for Rio im lost! it keeps showing me up the monster club "the week" . and a place called "fosfobox"...is that place any use?
can anyone please recommend places to find decent techno tunes?

Well did you find any good spots you can recommend to me?
