[12] In Exclaim!, Matthew Teklemariam rated Funeral for Justice an 8 out of 10, writing that "the music here is so energetic that it's invigorating" and "the production is a tight fit" that results in "a minor epic built from a surfeit of dissident spirit and Van Halen fanaticism".

[2] Janelle Borg of Guitar World stated that this music shows a progression in Moctar's songwriting and likened the playing style to Jimi Hendrix and Eddie Van Halen.

[19] In The New York Times, Ben Sisario called this release "a cri de coeur of screaming guitars and lyrics decrying the legacy of colonialism in Niger and throughout Africa" that "amps up the urgency" of 2021's Afrique Victime.

[21] In a feature on this album in Paste, Grant Sharples called it "punctuated by boisterous cymbal crashes and Moctar's signature shredding, it's an undeniable rallying cry" and "a celebration of Tuareg culture and, simultaneously, a denunciation of France's exploitation and profit from Niger's uranium reserves".

[22] Editors at Pitchfork scored this release 8.4 out of 10, declaring it among the Best New Music and critic Arielle Gordon praised the incendiary political lyrics: "it's impossible to miss—from the blood dripping off of the crows on its album cover to the screeching guitars that open its first song, it's the proud sound of rebellion, transposed from Tamasheq into a language that refuses to be misinterpreted".

[24] Jon Dolan of Rolling Stone called this "the band's most forceful album yet, tailor-made to melt minds at massive festivals" with "anti-colonial and anti-corruption declarations" accompanied by Moctar's guitar work.

[27] Editors at Stereogum chose this for Album of the Week, with critic Chris DeVille calling it "a fantastic record that should not have to exist", due to its response to the 2023 Nigerien coup, but continues that it is "too energized to be depressing", with "with shout-along slogans to go along with the rumbling rhythms and guitar heroism".

[32] A June 3 overview of the best albums of the year in Spin included Blu Wave where Jonathan Cohen stated "there's something at once ancient, sacred and ultra-modern going on here, and it's a welcome psych-rock rallying cry against the imperialistic assholes with whom we can never seem to dispense".
