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 of such recording method was the middle section of "Cassandra Gemini", edited from a lengthy jam session.
