Her first new music in four years.

Over the weekend, Solange teased a new project with a revamped website where one could sign up to possibly receive some snail mail from the True singer. The 86 people she chose received a poetry book called A Seat At the Table yesterday, which doubled as an announcement for a new album of the same title that will be released this Friday.

The album features guest appearances from Kelela, experimental cellist Kelsey Lu, Dev Hynes, former Destiny’s Child member Kelly Rowland, Tweet and more.

A Seat At the Table is out September 30. Download her poetry and lyrics book here.
