Always with a light touch, often with full force, Bersuit Vergarabat dishes out social commentary and political activism. "Madre Hay una Sola" is no exception, as Gustavo Cordera apologizes to Mother Nature for the damage done to her by the human race.

After all the bean sorting, cleaning, grinding and toasting we witnessed in our previous segments of Una Historia de Café, it’s finally time to boil up some water and do a little tasting, or “cupping,” as it’s known in laboratory circles. You might want to fire up your percolator; we have a feeling you’ll be craving some caffeine any moment now!

Belanova, the electropop band from Mexico, sounds like it was influenced by nightclub epiphanies, Japanese anime and sweet lollipops. "Niño", one of the songs off their album Dulce Beat, is a painful goodbye, adios, au revoir, arrivederci—but it’s somehow lightened by the constant use of the word “boy” (niño) to address the unlucky target of the bad news.

Once again Mili has to face Ivo. They’re sharing a roof after all. But this time she seems to have a strategy suggested by good friend and inexperienced but enthusiastic hairdresser Mariposa. Will it work? Heavenly houseguest Sister Catalina is leaving. The fridge is empty and we learn what planchar used to mean.

Here’s an emotional song to make quinceañeras scribble endlessly in their diaries and polish off entire Kleenex packets. Camila is a Mexican band that’s been touching sensitive teen souls since 2006—yet Mario Domm (the lead singer and brain behind the project) has been around longer than that, producing songs for artists as Alejandra Guzmán and Kalimba.

Natalia Oreiro’s life keeps getting better after her marriage to Dividos’ Ricardo Moyo. But she knows that when you get so much from life, you have to give something back, and that’s why she’s constantly trying to help people.

Landa Henriquez is a mother of three, Business Sciences graduate, entrepreneur, songwriter and singer. She’s also owner of a cute red descapotable and leader of the band. Not bad for a woman of 40.

La Vela is a small town in the state of Falcón, on the northwest coast of Venezuela, where every December 28th Los Locos [“The Crazy Ones”] arrive wearing colorful and elaborated costumes. The whole town becomes a party, with businesses closing and people dancing in the streets. It’s a tradition that could be in any magical realism novel and that desperately struggles to not fall into oblivion.

We’ve already seen some interesting, fabulous and downright curious things in the “mercado de pulgas” (flea market). But what about the people in there? They’re as colorful, amusing and charming as the goods in any stall.

Moenia may be considered one of the first modern, successful, experimental Mexican groups, finding commercial viability in a market normally dominated by old-style Latin crooners, Ranchera and Cumbia. Heavily influenced by ‘80s bands like Depeche Mode and The Cure, Moenia surged in ‘92 but fell out of public favor in the mid ‘90s when a key member quit. More recently, the reunited band has won over new fans with songs infused with ‘80s-style electronica.

Poor Bertolt Brecht should have suffered with Majo’s free version of one of his most well known poems “Ahora Me Llevan a Mí.” Her performance not only disturbed the German playwright’s sleep but also wasn’t delivered to the right audience, was it?

You can almost smell the coffee as Part 3 of our documentary takes us through the roasting process.

Guatemalan crooner Ricardo Arjona sings a long list of things he wants in his song “Quiero.” This video for “Quiero” was shot in the Dominican Republic and features the stunning Miss D.R. 2007, Massiel Taveras.

In Colombia, costeño y cachaco are almost opposite terms. Costeños, that is de la costa, people from the Coast, are usually depicted as festive, noisy, and colorful people who really enjoy killing time. Cachaco is usually the name given to people from the capital, Bogotá, and they’re characterized by elegance; they’re always dressed up and in control of their emotions. One group is seen as lazy, the other as boring. Regional differences aside, Bomba Estéreo is a fresh musical mix of both regions.

The quest for an excellent cup of coffee continues. Now we’re in the lab working to get rid of impurities by threshing and selecting the best coffee beans.
