Olfato translates to "sense of smell" or "scent." It's an interesting word because while common, it's less frequently highlighted in song lyrics compared to sight or hearing.
In "Cero Y Uno," the band explores the abstract nature of connection in a digital world. The lyrics repeatedly list the senses—hearing, sight, mouth, touch—and then include olfato as one of the ways to truly connect with another person, emphasizing a full, sensory experience beyond just digital interaction. It's a unique choice that makes the listener consider the depth of human connection.
"Cero Y Uno" is Café Tacvba's meditation on what it takes to truly reach another person. The singer lists everything communication demands: a voice loud enough to be heard, a photo that might outlast the moment, a body that can be touched, tasted, and smelled. Each verse strips connection down to its physical requirements.
The title, "Zero and One," points to the binary code underneath modern communication, the idea that a signal has to be broken down into the simplest possible units before it can travel from one person to another. The singer even admits doubt about whether the other person is real at all, needing faith that someone is listening on the other end.
By the end, the song settles on one answer: the only way to arrive is to make the journey yourself, all the way to where the other person is. It's a song about the effort behind being understood, told through the lens of signals, senses, and the leap of faith it takes to trust that a message actually lands.
