You don’t usually get rappers of Big Boi’s caliber releasing free mash-ups every week, but he’s been doing just that, labeling the releases #MashUpMondays. For his latest, he borrows the music of the Menahan Street Band for a soulful sound with a deep message. The picture above is from Big Boi’s personal collection—it’s his father. The two songs in the mash-up are Big Boi’s “Tremendous Damage” from Vicious Lies And Dangerous Rumors, and the Menahan Street Band’s “The World.”
