Editors at Bandcamp highlighted this as Album of the Day, with staffer John Morrison writing that the music "pushes the volume and energy to the max" and the songs "celebrate the power, beauty, and resilience of Black people everywhere".

[5] At The Line of Best Fit, Ims Taylor scored A New Tomorrow an 8 out of 10, calling the band "brilliant, vicious, breakneck hardcore" and this album "dark, forceful, and ready to leave you with ringing ears and shaking bones", summing up "you're left with the impression there's nothing ZULU can't do".

[8] Stephen Hill of Metal Hammer gave this release 4.5 out of 5 stars, calling it "the classic sound of punk rock, hardcore and powerviolence reimagined and rebred with both the liquid grooves and righteous protest polemic of the golden era of funk and soul" and "a wild ride, as Zulu can be destructively heavy one moment and gloriously euphoric and inventive the next".

[12] Revolver's staff tallied up the 25 best of 2023 on June 14 and included this release, calling it "a monstrously heavy metallic hardcore album that simultaneously subverts so many of that genre's predictable tropes".

[3] In a ranked listing of the best albums of 2023 from June 6, editors of Stereogum placed this at 20; critic Tom Breihan stated that "when operating at peak intensity, Zulu sound like worlds exploding".
