Juan Luis Guerra was the big winner at the Latin Grammy Awards last night (Nov. 8) at Las Vegas' Mandalay Bay, taking home honors for album of the year, song of the year, record of the year, tropical song and best merengue album for his single and album "La Llave De Mi Corazon."

"La Llave de Mi Corazon" also won for best engineered album, and the bachata icon was this year's Latin Recording Academy Person of the Year as well.

Ricky Martin won for best male pop vocal album for his critically acclaimed "MTV Unplugged" album and for best long-form music video for his "Unplugged" special. Laura Pausini's "Yo Canto" won for best female pop vocal album.

Calle 13 won best urban album ("Residente o Visitante") and best urban song, bringing down the house with a raucous performance of its winning track with Orishas, "Pa'l Norte," accompanied by the cast of Las Vegas' "Stomp Out Loud." The urban song honors went to Calle 13 and Panasuyo.

The telecast was a virtual advertisement for Las Vegas, a growing market for Latin headliners. The Latin Grammys paired several Vegas acts with nominees, opening with Martin performing his hits "Lola" and "La Bomba" accompanied by the Blue Man Group.

The show this year largely de-emphasized performance collaborations save for a few, such as Pausini's duet with Andrea Bocelli.

Best pop album by a group with vocal went to breakout act La Quinta Estacion for its album "El Mundo Se Equivoca." Best new artist was Mexican brother/sister duo Jesse & Joy. Aterciopelados won best alternative album for "Oye."

The eighth annual Latin Grammys were carried live on the Univision Network.
