Hip-hop and rap was the closest thing to the 70's music revolution that existed through the 80's and 90's. Hip-hop artists sampled many of the soul and funk legends by adding parts of older songs into their own music, or looping instrumental parts of old funk and soul songs and adding heavier drum beats and rhythms to it. The closest to funk in the hip-hop movement was Digital Underground, led by Shock G. 2Pac Shakur came out of Digital Underground. George Clinton had officially branded Digital Underground as "Sons of the P". Other good groove oriented groups like Jamiriquai came around every now and then, and it would be fair to say that many artists have at least some elements of the original funk and soul in their music, but there was no organized movement.
