Prior to his performance at the University of Louisiana at Lafayette on Monday [April 18], Lil Wayne received the key to the city for his philanthropic work.

The Young Money leader partnered with TIDAL to create a competition called TIDAL’s Social Wave for Change. It involved college students and its purpose was to make contributions to the Flint water crisis and raise money for the Special Olympics. The fraternity brothers at University of Louisiana at Lafayette raised nearly 7,000 bottles of water for Flint, Michigan and as a result, Lil Wayne performed at their school for free.

The Hollygrove rapper was met backstage by Mayor-President of Lafayette, Joel Robideaux, who honored him with the key in the form of a chain.

We appreciate what you and TIDAL have done on behalf of the philanthropic efforts and we’re so proud of our Ragin’ Cajuns, Alpha Phi Alpha for what they did, and we wanna present to you a very special key to the city that we made specifically for you. One of a kind, nobody else has it.
