From Brazil I would recommend stuff from Carlinhos Brown and Airto Moreira (Samba De Flora being my particular favourite) Also if you've got iPlayer take a look at Huey Morgan's Latin Music Adventure from last Friday which covered Brazil. Might give you a few tips.Thanks for those, too late last night to play, I will have a listen later today. I do know quite a few of them already. Can you recommend any albums with lots of drums, African or Brazilian?
In terms of African music with lots of drums then there're the Apala and Fuji styles from West Africa which are highly percussive but my knowledge is a bit vague in terms of albums. The Soul Jazz label has recently brought out compilations of both styles which might point you in the right direction. Also check out the two Pat Thomas and Kwashibu Area Band releases on the Strut label - you really are dead from the neck up if you don't immediately start tapping your foot to either of them.
