You know what a calavera is, no? If you see one, especially on a sign in a former war zone, be very, very careful. Soldiers from Brazil, Colombia, Venezuela and the U.S. came together to reduce the need for these signs in Central America… reclaiming fields filled with anti-personnel mines so that farmers can return to using them for crops.

The effort to de-mine Central America is truly an international one, with assistance coming from the U.S., Germany, Spain, France, England, Japan, Canada and Sweden (who’s ambassador is featured here, speaking eloquent Spanish). Also we hear from soldiers on the pleasure of serving a mission of peace, as opposed to one of war.

From their 2010 album, Modular, The Pinker Tones bring us this surreal song. So much happens to this duo while stretched out under the sun. Funny thing is: some of the crazy stuff they think of is plucked straight from real life.

In their video for the track “Invisible,” the Pinker Tones play with the idea of invisibility. They hide behind newspapers, trees, turtlenecks, boxes, balloons, and sheets right in the middle of downtown Barcelona. Don’t expect a huge vocabulary! It’s just a silly, funny way to express the desire for invisibility.

The Krayolas have been around for a long time, and their work, talent and dedication shows in “Little Fox.” We warn you: this song will be stuck in your head for several weeks.
