Insane Clown Posse recorded a track "Is That You?" featuring Kid Rock.

Kid Rock recorded a song "Picture" with Sheryl Crow.

Sheryl Crow performed "He Needs A Kidney" with Elvis Costello.

Elvis Costello recorded "My Dark Life" with Brian Eno.

So Insane Clown Posse have an Eno number of four. #EnoNumbers #SixDegreesOfBrianEno

For the curious:

ICP featured Kid Rock on their first Insane Clown Posse album.

Kid Rock recorded two songs with Sheryl Crow.

Sheryl Crow's first album was produced by Hugh Padgham.

Hugh Padgham also produced Bowie's album "Tonight".

And of course, Bowie and Eno worked together on "Heroes".
