Here's a preview of the new Wisin y Yandel video, "Te Siento." The popular duo have a new album coming out next week -- sort of.  It's a re-release of their current hot album La Revolucion and you'll see it listed as La Revolucion, La Revolucion:Evolucion or La Evolucion. Whichever name you pick, "Te Siento" is one of the new videos on the release.

The evolution of La Revolucion includes five new tracks and remixes while the companion DVD contains eight new videos including "Imaginate" with T-Pain. So if you feel like you already have the songs, you might well go for a new batch of videos. 

November is traditionally a time that big, new releases hit the street and in the last couple of weeks Alejandro Sanz, Victor Manuelle, Olga Tanon, Carlos Vives and Xtreme are among the artists that should give us something to be thankful for as we swing into serious fall and long evenings.

There were a few big albums, among them Shakira's She Wolf that were scheduled to be released yesterday, but it looks like they've been put off for a week . Look for them next week!

Calle 13 was the big winner at this year's Latin Grammy Awards, turning all five nominations into winning tickets. You might think that this is just another duo that glories in rapping to that 'dem bow' rhythm.

Well, they rap. They often do it to the rhythm so familiar to reggaeton fans. But that's not all they do. They also fuse their rhythms with other beats. They feature instruments from many of the countries in South America. They have a wicked sense of humor. And when they're angry, they are usually angry about injustice as they perceive it.

Calle 13 isn't just another band from the mean streets of Puerto Rico -- in fact, the brothers consider themselves middle class. So what does middle class urban music from Puerto Rico sound like?

It sounds like something different with each new album.

Argentine folk singer Mercedes Sosa died on Oct. 4, 2009 so she never got to personally pick up the Latin Grammy for her album Cantora, although there was a touching tribute to the iconic singer during the ceremony.

Cantora is an album of collaborations with other artists, some old friends, others newer singers that might seem unlikely to be singing with the folk diva. The list includes Shakira, Gustavo Cerati, Lila Downs, Julieta Venegas and Franco Da Vita.

But the song I found most touching was the collaboration with the evening's big winner, Calle 13.  How does Mercedes Sosa mesh with Calle 13, you ask?

"Cancion Para Un Nino En La Calle" (Song For a Street Child) is a theme you will find in both the songs of Mercedes Sosa and Calle 13. Written by Silvio Rodriguez, it intersperses Sosa's distinctive, plaintive voice with soft rap performed by Rene Perez, Calle 13's Residente. The counterpoint between the two styles of singing really works in this number. Check it out.

By the way, there are ten brand new videos and songs currently posted  in the Latin Music & Songs and Videos booth, including numbers by Alejandro Sanz and Alicia Keys, Ednita Nazario, David Bisbal, Carlos Vives and more.
