Here's a baião-based funk groove from Airto:
That is, Airto's feet are doing baião, everything else about the tune is just early 70's funk jamitude. The accents on the floor tom are pretty subtle; he just plays the right hand a little stronger than the left.
Get Airto's Virgin Land at Amazon.com. You should really be able to get this one at your local used vinyl store, though. I don't link to iTunes, but you could try them, too.
