Theres a great UK label for all things Brazillian called Far Out Recordings, which includes music by a great UK singer Heidi Vogel, who did a lot of broken beat stuff in the early 2000s and has recently been doing a fair bit of Brazillian material
If you get the chance i recommend seeing her live as she's a real force of nature, and when she gets unhinged and goes into scats and the like she's hard to beat.
