Gucci Mane may be the hardest working man in Hip Hop.

So it's no surprise he was honing his craft during his time in federal prison.

In a series of snapchat videos Gucci displays all his raps that he wrote while he was locked up, which are now on the walls of his studio.

Gucci's next album Everybody Looking is set to drop on on July 22, so expect to hear some of these bars on it.
