With Solange's new album A Seat at the Table out Friday, her Lil Wayne collaboration "Mad" has already surfaced online.

As we previously mentioned, the younger Knowles sister announced only Tuesday her followup to 2012's True will be released tomorrow. She has described the record as a "project on identity, empowerment, independence, grief and healing."

In addition to Weezy's guest appearance, A Seat at the Table features Kelly Rowland, Dev Hynes, Q-Tip, Sampha, Moses Sumney, Kelela and BJ the Chicago Kid, among others.

Hear "Mad," which additional vocals from Moses Sumney, below.
