Last month, the Village Voice announced the return of the 4Knots Music Festival, and now, the long-running NYC alt-weekly has released details about the official 4Knots After Party. The 18+ event will take place on June 29 at Brooklyn's Music Hall of Williamsburg at 8PM, with Lil B headlining alongside special guests.

“Lil B, or the BasedGod, is a rapper, songwriter and author who has recorded both solo and with the Pack,” reads the fest’s official site. “The San Francisco-based artist is known for his extensive use of social media sites MySpace and Twitter. Lil B will be taking over the 4Knots After Party with a night full of special guests. The official after party will be held immediately following the all day 4Knots Music Festival.”

This year’s festival boasts an impressive lineup featuring the likes of Kurt Vile and the Violators, White Lung, Reigning Sound, Fat Tony, Heliotropes, the Babies, Parquet Courts, the Men and Marnie Stern.
