Full transcript, in English.

Is the new album, Oye, back to basics?

Hector: We started as a traditional rock and roll band – using bass, guitar, drums. We then evolved, adding instruments and getting to an album like Caribe Atómico, where we experimented with electronic music and used the studio as an instrument. Since then, we’ve returned to using our old instruments and using less electronic sounds, where the live drums are again present on this new album. Even though the electronic has been lowered, it is still present. The sound of a band is more present on the album.

Ok, let's retake it, let's do it again. No, no, let's continue, you guys can edit.

It’s simply using different instruments from album to album. In this new record, Oye, the drums and the electric guitar are more present than in the past albums using less electronica. That’s why it sounds more organic. More rock-like.

Do you think a protest song still has the same power today to "change" the world?

Andrea: I think that any attempt at change is cool and healthy. And any massive change starts with a personal change. Even the attempt an individual makes writing a song that tries to change things, the change starts right there, from the person that wrote the song. And if that song is heard by many people, the change starts to grow and grow. Any revolution, any change on a global scale has to start with individuals. And that’s the goal of writing a song like this and that’s the goal of creating music, to communicate, and shifting that energy so it becomes more positive, cooler. So that we live in harmony, which is what our music is trying to communicate: harmony.

So, who has more of a chance of transforming U.S. pop culture, Aterciopelados or Ugly Betty?

Hector: I think that every message reaches a certain segment of society, to certain fans, to people who need it or who have certain affinity. We connect with kids who have ethical and musical affinities with what we do, where the message in our lyrics has something to do with their lives. A show like Ugly Betty probably connects with another type of crowd.

Andrea: More mainstream.

Hector: The channels on which Betty is shown have a massive audience that reaches into the millions. People have to go look for our records, go to our concerts. Betty is on TV in their homes. Like everything there are ideas that interested ones will recieve while others won't. While some ideas will be recieved by a few.

Andrea: I haven't seen Ugly Betty.

Hector: I don't know what sort of change it will produce, but regardless it's a show that was widely seen in Colombia. It was different, cool, as a new way of doing soaps, a new way of telling a story with more realistic characters.

How has the female factor in rock changed since "Florecita Rockera?"

Andrea: Yes, definitely, the number of girls in Latin rock has dramatically increased. When we started, there were few. And right now, they are successful and very well promoted, that’s cool. What I think, regardless of how many women or men there are, what’s important is that everyone’s female energy needs to be “on,” including in men. At that moment, not only the music scene, but also politics and culture would benefit. Feminine energy is needed for less competition, for more love, comprehension and generosity. In some ways, the notion that there are more women in rock, gives me hope that this will happen.

As Colombian artists, what's your take on cocaine?

Hector: Colombia has had the sad story of being involved in the drug wars, for being a country where coca is cultivated. And for this reason we’ve paid a high cost in lives, because of problems with drug traffickers, spraying of lands which also includes parks and we’ve seen that this hasn’t solved or lowered the number of illicit plantations. I think the problem lies more with the consumption of drugs, and that consumption we’ve seen everywhere. But looking at the data, the United States is the country that consumes the most, due to its its large population. The problem needs to be attacked on that side, because for many years in Colombia the problem has not been solved.

Andrea: We are more in favor of policies like those of Carlos Gaviria Díaz, who has proposed the legalization of drugs as a strategy, which is very interesting for a country that receives so much negative criticism. That would be an interesting option.

What is on your iPod? What are you listening to now?

Both: We don’t have iPods.

Andrea: Antony & The Johnsons.

Hector: Yes. A boy from England, is he from England?

Andrea: I don’t know but he sings so beautiful, very romantic. Cerati.

Hector: There is this French group called Phoenix, I have been listening to their last album a lot. World music, music from Pakistan, desert blues music from a band called Tinariwen, I like that a lot. And - Choquitown.

Andrea: Choquitown!

Hector: It’s a group from Colombia, electronica, hip hop and more west coast sounds. It's also very popular in Colombia. What else?

Andrea: I always forget what I’m listening to when I’m asked on the spot. Natasha Atlas, Lhasa, Lila Downs.

Hector: Jorge Drexler, he has a new record called 12 Segundos de Oscuridad. We just came from Spain and have been listening to some Flamenco music.

Andrea: Estrella Morente

Hector: Estrella Morente, Los Delincuentes, Kiko Veneno.

What is the last book you read?

Andrea: “One River” by Wade Davis, it’s a beautiful book, the story of some ethnobotanic explorers who traveled to the Amazon, to the Putumayo region and to Bogotá as well. It's very pretty.

Hector: Ursúa, it's also the name of a Spanish conqueror, written by William Ospina, about this odyssey of America’s conquest in the region of Colombia.
