Gnu, when you ask this question you are also re-introduce the topic "What is folk?".

To expand this conversation, if roots Hip-Hop is considered part of folk music, then examples of jazz/Hip-Hop fusions should be included in this discussion.

See these comments from TalkBass discussion forum:

Don't forget Spearhead! And if you want to check out some of the roots of jazz/hip-hop fusion be sure to look into Gil-Scott Heron. Lauryn Hill's "Miseducation" also has some fine basswork."
