I love her voice much but that Suba is light years beyond BG in interest as far as a solid platter is concerned. I had picked up those two Bebel's when they came out respectively and the second was quite a yawner esp after hearing her on an Arto Lindsay/Towa Tei thing long ago.
Cibelle, who voxes on Suba, was a good start but tiresome in short time. Her new one seems very very laid back from samplings.
Recently "got the wife" that new Rosalia DeSouza as she reminded me of a smoother voiced Marisa Monte (who's early stuff is all good).
And I sure wish Lillian Vieria from that Zuco 103 group would do something great - she seems like a lot of fun!
