La Realidad De Los Sueños

The set includes eighteen LP vinyl records, a photo book of behind-the-scenes photography, credits insert, a poster, 3D glasses, and two pins.^[2] All of the band's then-current official discography, excluding Live and Scabdates, is included as well as a previously unreleased demo album of De-Loused in the Comatorium, titled Landscape Tantrums.^[3] This session was overseen solely by the band's guitarist Omar Rodríguez-López, who stated in an interview that the two-track references were bootlegged but that the mixes were preserved and stored in his vault for twenty years. It was also the first project that he and Jon DeBaun worked on together, according to the same interview. Furthermore, Rodríguez-López mentioned the difficulty in working with Universal Records to release the box set. He states, "[Universal] literally are not using the master that came from me, the one used for the original analogue pressing. They have the digital master, from which they made the CD and the digital releases." However, the included releases were eventually pressed from vinyl lacquers that were remastered by engineer Chris von Rautenkranz, who wanted to give the sound more space and to make it more livelier and organic.^[4][5]

Also included in La Realidad De Los Sueños are an unreleased song from the De-Loused in the Comatorium sessions titled "A Plague Upon Your Hissing Children" and a version of Eunuch Provocateur recorded in the same period.^[6] A Plague Upon Your Hissing Children had been bootlegged and circulating on the internet for years under slightly different names before being included in the box set.^[7][8] Such is the case for this version of Eunuch Provocateur and also Concertina which are tracks on their earliest release, Tremulant. These versions of the tracks were rerecorded during the De-Loused in the Comatorium sessions under Rick Rubin.^[9] While certain unreleased songs and B-sides like these and Mr. Muggs were included in the box set, the absence of others like Ambuletz and the rerecorded Concertina are especially intriguing.^[10] The name of the album likely refers to a lyric in Concertina, "la realidad de tu sueño," much in the same way Landscape Tantrums is taken from a lyric in Cut That City from the same inaugural release.

The box set itself is a rhombus-shaped encasing that pulls apart to reveal the LPs and photo book. It sits upon a carboard stand and features a series of dream-themed, surrealist collage artworks made from the band's previous releases.^[11] The LPs are pressed on black vinyl. The record label overseeing the box set's release, Clouds Hill, priced it at £320.00 GBP with a limited five-thousand copy release.^[2] It sold out in the U.S. well before its April 23, 2021 release date.^[12]

Regarding the box set, Rodríguez-López, stated in an interview: “It’s a snapshot, the only proof that I have that that person, now unrecognizable to me, once existed and did these things, had these experiences. It’s like finding a beautiful surprise package that becomes sentient and awakens us.” Moreover, lyricist and singer, Cedric Bixler-Zavala, referred to the anthology as a “time machine.”^[13]

La Realidad De Los Sueños received generally favorable reviews. Rolling Stone described it as "some kind of trippy, seemingly bottomless treasure chest." They praise the box set's art, imagery, and overall music selection.^[13] Flood Magazine lauded the collection as both a "forward-back time machine of craft, multiculturalism, and innovation stuffed into an immense treasure chest/magician’s hat filled with a seemingly never-ending array of tricks and triumphs." The magazine compliments the production and the inclusion of previously-unreleased material.^[18]

Louder Sound plaudits Landscape Tantrums and, in general, describes the band's discography as "music as science, science as emotion, emotion as inspiration, put together by crazed geniuses with virtuoso skills."^[19] Kerrang! likewise touches upon all of these points while also claiming that The Mars Volta has created some of the "most genuinely progressive music in rock history."^[20]
