Some of the material which would end up on
Frances the Mute, including "The Widow" and "Miranda That Ghost Just Isn't Holy Anymore", pre-dated
De-Loused in the Comatorium, having been originally demoed by
Omar Rodríguez-López in the early days of The Mars Volta. While touring in support of
De-Loused, the band would incorporate more and more extended improvisational sections into some of their songs, often trying out new ideas. Parts of "Cygnus....Vismund Cygnus" ("Facilis Descenus Averni" and "Con Safo") were first performed live in the middle of "Drunkship of Lanterns" (as heard on
Live EP) and "Take the Veil Cerpin Taxt" respectively, while parts of "Cassandra Gemini" originated from improvisations during "Cicatriz ESP" (as heard on
Scabdates). The album was initially to be titled
Sarcophagus. Rodríguez-López arranged and produced the recording sessions himself. Unlike
De-Loused in the Comatorium, which was recorded in producer
Rick Rubin's
mansion, sessions for the new album took place in multiple studios, with most tracking done in what Rodríguez-López described as "a shithole… Basically a warehouse with one little air conditioner on its last legs, awful wiring and a console you couldn’t rely on". Rodríguez-López took the additional step of recording the band member separately before layering the various tracks to create each song. Drummer Jon Theodore was the first to record his parts, and he spent time arranging and mapping out the songs with Omar and in the process figuring out what the rhythmic structures would be stated on the recording process. "This is the first time I've ever been so methodical about recording. Normally I would go into the situation with as good an idea as I could, whether that was from performing the songs on tour or having a general road map. But this was the first instance where I considered every single hit all the way through, every figure up to and including every change. There were no question marks. So when I was tracking with the metronome it was just a question of right or wrong." An exception to this recording method was the middle section of "Cassandra Gemini", edited from a lengthy jam session. Tracking this way had a mixed reception in the band; Theodore and bassist
Juan Alderete responded well to the individualistic approach while keyboard player
Isaiah "Ikey" Owens didn't like it at all. However, as Rodríguez-López stated, "People filling in ideas can become tedious and counterproductive. You find yourself working backwards. When you're in the studio 'what ifs' are your biggest enemy, so my general rule is, if it's something you can't live with—if a sentence begins with 'I can't' or 'I will not'—then we examine it. But if it's 'maybe we should' or 'I think that' then it's like, hey man, full steam ahead. Not that there isn't a lot of refinement to what we do—obviously there is— but I consider it a balance of raw energy and refinement."
Sound and lyrics Frances the Mute is comparable to The Mars Volta's 2003 release
De-Loused in the Comatorium, with its cryptic lyrics and highly layered
instrumentals, although the
progressive rock influence is stronger on
Frances the Mute than it was on
De-Loused in the Comatorium. "The Widow" is notably the only short, pop-structured song on the album, although the last half of it features a lengthy, non-radio-friendly outro of manipulated tape loops of organs and electronic noise; for the single release, this part was edited out. Ambient noise plays a larger role on
Frances the Mute than it does on
De-Loused in the Comatorium: "Cygnus....Vismund Cygnus" ends with the recording of children's voices and passing cars (made by Omar Rodriguez-Lopez in front of the house where he used to live with Bixler-Zavala and Ward), while the first movement of "Miranda That Ghost Just Isn't Holy Anymore" ("Vade Mecum") features 4 minutes of
coquí frogs (credited as "The Coquí of
Puerto Rico" on the album sleeve) singing while a thick soundscape is slowly built from guitars,
synthesizers and Bixler-Zavala's voice. According to Rodriguez-Lopez, "Miranda..." was influenced by the music from western movies: "I'm a big fan of
spaghetti-western and I think it shows on "Miranda". Our
Morricone-influence has always been there, but on "Miranda" we let it all out. The last song ["Non-Zero Possibility"] on the
last At the Drive-In album, the best thing we ever did by the way, had touches of spaghetti-western." The fifth and final song of the album, "Cassandra Gemini", clocking at 32 minutes and 32 seconds is to date the longest studio song released by The Mars Volta. Rodriguez-Lopez said of the song: "Ever since I was a teenager, and had various listening experiences with the likes of
King Crimson,
John Coltrane, and
Miles Davis's
Bitches Brew, I've always wanted to do something like "Cassandra". Something deformed and out of control. Something enormous and violent, a whole album fitted into one composition. Something ruthless that no one can remain careless to." Regarding the album's lyrical content, vocalist
Cedric Bixler-Zavala stated: ==Release history==
