http://www.drumlesson.com, which includes online multi-media courseware I found helpful for bongo. Courses are something like $6-9 USD, and can be accessed with no constraints for, I think, 60 days. Includes transcribed rhythms, video clip of the player (from over the shoulder for bongo) and audio. I use RealPlayer.
If this site and drumlesson.com merged I think we'd have truly the ultimate online resource.
