Misión Cumplida - Jenni Rivera - Mission complete: Ten years after her death, the voice of Jenni Rivera continues to be heard by her fans. The children of the late banda songstress released "Misión Cumplida," the first single of a posthumous album of unreleased demos she recorded before her death. After Rivera's son Johnny Lopez found demos with Rivera's voice he and his siblings - including Jacquie Rivera, who is the CEO of Jenni Rivera Enterprises - decided the best way to give back to Jenni's fans was through releasing some of the music she had worked on.
