Background and music
The mixtape adopts eclectic production styles and further explores the music genres that Lil B experimented with in his career, including cloud rap, hyphy, trap and rap rock. The mixtape also features use of various samples. At least four tracks use samples from The Diplomats album, Diplomatic Immunity and the track "Lil B" uses the beat from LL Cool J's 1999 FUBU commercial song "Fatty Girl." The track, "Im the Rap God", features Lil B rapping over the instrumental version of System of a Down's 2001 song, "Toxicity", which was described as "a drunken-style karaoke freestyle" and "your friend's blunt-smoking roommate doing an impression of MC Ride on the choruses." The track, "G.O.R. (God of Rap)" lasts for ten minutes and starts with a sample from 1991 film Barton Fink, accompanied by atmospheric guitar and drum beat, before evolving into a sample by symphonic metal band Nightwish. "Twurk Sum" contains an interpolation of "Homelife is a Drag" by punk band No-Cash. The song "Im Gunna Be a Doctor" uses a sample from Twista's 2003 song, "Slow Jamz", which was produced by Kanye West.

Production on the album was handled by a range of people, including longtime collaborators like Keyboard Kid and Lou Pocus, as well as Mac Miller.

The lyrics of the song range from confessionals, free associations, motivational speeches, and uncensored sex talk. The themes include brooding, anger at the prison industrial complex, and emotional conflicts.

Critical reception
The album generally received mixed to positive reviews from music critics. Consequence of Sound reviewer Pat Levy described the album as "complete and complex piece of work that Lil B has produced to date" and wrote that it "showcases his ability to maneuver his persona over a number of different production styles." Nevertheless, he also stated: "Maybe his 'Control Response' is far-fetched for his talents, but it's not like he's struggling for relevance." Christopher R. Weingarten of Rolling Stone described the album as "his grandest gesture yet." He commented that "the mixtape reaches the highest highs of the best Lil B songs," while criticizing the "id-fueled" sexual fantasies, which he thought "end up stealing the spotlight from an album that's at its best when showing its sensitive core."
