Day 0662 - Done by the Forces of Nature

The Jungle Brothers "Done by the Forces of Nature" (1989)

 
The Brothers beefed up their classic rap sound with elements of jazz, world music, house, funk and Afrobeat.  According to the book, the group were accused of selling out, but history appears to have vindicated the them, with the album being pegged quite high on several ranked lists, not to mention retrospective reviews generally lauding the album.

Day 0566 - Planet Rock - the Album

Afrika Bambaataa & Soulsonic Force "Planet Rock - the Album" (1986)

Amazing achievement, in that Bambaataa manages to be an early pioneer of hiphop, but also, through splicing various synth-heavy beats (including cuts by Kraftwerk) he also laid the groundwork for House music and other forms of electronic experimentalism.

I could easily see this being a reference point for bands as varied as early Red Hot Chili Peppers through to the Chemical Brothers.   Rage Against the Machine would go on to cover "Renegades of Funk" and the Beastie Boys would sample Bambaataa.

A true visionary musical force.
