Disco4

The album was partially constructed from a series of collaborations the band had made over the years; some, like "Hate You" with JPEGMafia, "Delicious Ape" with Xiu Xiu, and "Mass Grave" with Soccer Mommy were previously released, but also incorporated new tracks like "Power Fantasy" with 100 gecs and two new, non-collaborative songs, "Cyberpunk 2.0.2.0." and "These Days 2.0.2.1.".^[4] Health described the record as " a collection of original collaborations with artists we admire", in contrast with their past remix albums, with the Disco title being maintained for continuity.^[5]

Singer Jake Duszik said that there could be a "fair amount of awkwardness" in the collaboration process, with it being like a "blind date", but he also said it avoided being stuck in a "cyclical rut".^[6][7] According to John Famiglietti, the band aimed to ensure "true collaboration" for each track, with the initial idea not "fully fleshed out"; some were started by the collaborating artist.^[6]

"D.F. Looks" was based on an remix of "L.A. Looks" by Brothel, and "Mass Grave" was derived from a session with Purity Ring.^[7] The name of "Cyberpunk 2.0.2.0." is based on the tabletop role-playing game of the same name, Cyberpunk 2020, since Health made an appearance on the soundtrack of its then-upcoming video game adaptation, Cyberpunk 2077. "Delicious Ape" with Xiu Xiu was based around a sample of an ape.^[7][8] For Part II, the band contacted Trent Reznor of Nine Inch Nails with the expectation that they wouldn't hear back, but it became "very real" when they got a vocal track.^[6]

Being a collaboration with a number of different artists, Disco4's tracks incorporate elements of a number of different genres, including electro-punk, EBM, post-rock, and trap.^[9] Part II was described by Simon K. of Sputnikmusic as including more metal elements than the first half.^[9][10]

Part I was generally well-received, with KEXP saying "The album coheres surprisingly well, with the sound being a dark, ominous blend of industrial, noise-rock, metal, and electronic styles."^[16] Flood Magazine's Mike Lesuer stated that the tracks "don’t feel out of place, half-cocked, or ill-conceived", with the album "weirdly [feeling] like one of the most cohesive musical capsules for 2020".^[11] Simon K. agreed, stating all but one "feels and sounds surprisingly well developed and expertly handled", but criticised a "couple of stylistic clashes".^[9]

The second half received a score of 77 out of 100 on review aggregator Metacritic based on five reviews, indicating "generally favorable" reception.^[12] Allmusic's Heather Phares described the melding of genres as working "remarkably well".^[13] Simon K. called it a "fantastic album" but perceived it as becoming "samey" after its midway point.^[10] Kate Crudgington of The Line of Best Fit called it "proof that HEALTH’s talent and appetite for collaboration is as potent as ever".^[14] Kerrang! writer Paul Travers stated that while he thought it "isn't perfect, it's definitely worth your time".^[15]
