Meanwhile, the album's production was handled primarily by Metro Boomin, alongside Bijan Amir, Cubeatz, Dre Moon, and Southside.

[6] Sheldon Pearce of Pitchfork praised the chemistry between the rappers, its Halloween aesthetic and Metro Boomin's production, stating: "It's short and cohesive, an enjoyable and uncomplicated 33 minutes of sheer exhilaration, filled with stings, itches, and cold chills.

[13] Gary Suarez of Consequence said, "Where the Super Slimey too often felt like a requisite Xanax-blasted victory lap, one notably soft on hooks [...], Without Warning exudes vitality and menace".

[8] Online publication HotNewHipHop stated that Without Warning is "the rap equivalent of a slasher flick: gory, over-the-top, and a lot of fucking fun.

Big bells, eerie piano, reverby bass, and sci-fi synths set the tone, but the way he deploys them shows the most progress.

Both are experiencing crazy levels of success they might never have imagined, both are carving their own unique lanes through rap while staying true to their styles.

"[17] In a mixed review, HipHopDX's Trent Clark stated: "Like most projects that get recorded without the guise of a meticulous A&R, Without Warning's billing never exceeds the expectations of any artist—rapper or producer—let alone offer a glimpse of what allows these individuals to rank amongst 2017 Hip Hop's most popular figures.
