Before Wiz Khalifa was a household name, he was on the mixtape grind. Before he was selling out stadiums, he was shelling out free material and making fans all over the internet. A few years later, the guy was everywhere.

Wiz is another example of how free music (and the internet) can lead to fruitful careers. If it wasn't for the highly popular Kush & Orange Juice mixtape, who knows if we'd even be writing this article today.

It didn't stop at Kush & OJ either, Khalifa continued to put out solid mixtapes likeTaylor AllderdiceCabin Fever (both 1 and 2), and 28 Grams. He just recently put out the collaborative freEP with Ty Dolla $ign, and we can't forget about B.A.R. either. The guy's a workhorse!

It's all paid off for Wiz, he continues to stay towards the top of the rap game, where he's been chillin' for a few years now. Today, we're going to take a look at some of the free music that helped him get there with a TBT Mixtape Khalifa.
