Looking at this challenge, I got to thinking about Kevin Bacon's actual rock band, The Bacon Brothers. Then I did a search for Six Degrees of Separation (fig.1). Then I thought, hey I bet Oscar winners the Three 6 Mafia would be a fun challenge. Thus this task. I looked at the pages for both the Bacon Brothers and the Three Six Mafia. I decided to start working from the Bacon Brothers.

The Bacon Brothers
The Jayhawks

Black Eyed Peas
Del tha Funkee Homosapien

--------
NOW, if one looks at Three 6 Mafia's page at Allmusic, Mobb Deep is listed under their similar artists. However, Three 6 Mafia is not listed as a similar artist on Mobb Deep's entry in Allmusic.

Some might say, good enough. I say no!

SO... a little thinking and half a step of backtracking later...

(all the above, then)
