Folk Rap.
Sounds about as appealing as sex with Jabba the Hut doesnt it?
But who would have thought that a folkified cover version of a rap song could be so good. Its dope!
Check it out - Brent Runyans cover version of Public Enemys Bring The Noise
And if you want more - A 'Joan Baezesque' version of NWAs 'Straight Outta Compton' - by the ex-Veruca Salt lead singer. (or try this link)
Makes you wonder what other unfathomable versions could be done!!
