The mixtape features production from Chuck Strangers, Kirk Knight, MF Doom, Statik Selektah, DJ Premier, Lee Bannon, Oddisee, Navie D, and Bruce Leekix.

 The extended play has inverted into the re-release from the mixtape, titled Summer Knights EP; released on October 29, 2013.
 On May 22, 2013, Joey Bada$$ announced the official release date of his next solo project, Summer Knights EP on June 12, 2013, which marks as the one-year anniversary release of his breakthrough mixtape 1999. On May 28, 2013, Bada$$ announced Summer Knights will no longer be an EP, and instead announced that this project will just be a full-length mixtape. He revealed that the mixtape will feature 17 tracks, along with the production, which will be handled by Statik Selektah, Lee Bannon, Chuck Strangers and Kirk Knight, among others.
 The mixtape features guest appearances by his fellow Pro Era members, along the additional production by DJ Premier, The Alchemist, MF Doom and Oddisee, among others. On the announced release date, Joey Badass revealed on Twitter that the mixtape was pushed back until July 1, 2013. This was also said to be a "rest in peace" mixtape to Pro Era founder and close friend Capital STEEZ, further indicated in the 16th track entitled "#LongLiveSTEELO."
 Summer Knights received generally favorable reviews from music critics. At Metacritic, which assigns a normalized rating out of 100 to reviews from mainstream critics, the album received an average score of 66, which indicates "generally favorable", based on 10 reviews. Exclaim! magazine's Chris Dart found Badass' rapping versatile and skillful, and said that the mixtape is exceptional at its high points, despite being a few unnecessary songs overlong. Abrea Armstrong of XXL felt that his lyrics are still confident, but now informed by new life experiences, and recommended Summer Knights to hip hop buffs rather than Badass' typically teenage listeners, although she wrote that "Joey is here to prove that they're one in [sic] the same." In a mixed review, Phillip Mlynar of Spin felt that Summer Knights lacks the immediacy of his early music and found his rapping dull and enervated, which he mused is a result of pressures and expectations from the music industry.
 On December 24, 2013, XXL positioned it at number 19 on their list of the best mixtapes of 2013. They commented saying, "One thing is clear when you listen to the tape, he’s not kidding around, as he unleashes some bone-shattering bars with a calm cold assassin-like demeanor. 1999 was more of a coming-of-age tale from Joey while Summer Knights provides as a worthy follow-up illustrating his maturity and growth. Pro-Era’s boom-bap ’90s chill-vibe is still prominent in the album, however with an extra kick making it sound very refreshing."
