Jesse & Joy Are Big Winners at Latin Grammys Jesse & Joy, the sweet-singing, brother-and-sister pop duo from Mexico, were the big winners at the 13th Annual Latin Grammy Awards in Las Vegas on Thursday night, walking away with four trophies, including best song and best recording for their hit single "Corre!" Juanes, the veteran Colombian rocker, won album of the year for his "MTV Unplugged" release. Best new artist went to 3Ball MTY, a trio of electronic musicians from Monterrey, Mexico, who rose to prominence this year when their single "Inténtalo" topped the Billboard Latin charts. Their name is code for "tribal Monterrey." Juan Luis Guerra, the Dominican musician who came into the ceremony with six nominations, won producer of the year for Juanes' "MTV Unplugged" and shared the stage when that album won the top honor. Arturo Sandoval, a jazz trumpeter, won three Latin Grammys in all, two for his album "Dear Diz (Every Day I Think of You)." Lila Downs, the Oaxacan folk singer, won best folkloric album for "Pecados y Milagros." The Colombian singer Fonseca took the award for best tropical fusion album, and Los Tucanes de Tijuana, known for their narco-corrido songs about drug lords, won best norteño album for "365 Dias," the band's 32nd release. Milly Quezada brought home the Grammy for best contemporary tropical album for "Aqui estoy yo." The award for best ranchera album went to the veteran Mexican singer Pepe Aguilar for "Más De Un Camino." Yalil Guerra, a Havana-born contemporary composer who lives in Los Angeles, won this year's trophy for best classical contemporary composition for his work "Seduccion." The performances ranged across Latin genres, from electronica to folk. The producers brought performers from different generations together. Juanes performed his song "Fijate Bien" with the guitarist Carlos Santana, and Prince Royce, the young Bachata star, sang "Incondicional" with Joan Sebastian, the veteran Mexican songwriter. Mr. Downs was joined by the Colombian singer Totó La Momposina and the Mexican accordion master Celso Piña for a "Zapata Se Queda," Though he was not the night's big winner, Mr. Guerra, the Dominican singer and songwriter, brought the audience to its feet and got people dancing when he performed his hit "En El Cielo No Hay Hospital," a merengue built around a saxophone riff and syncopated tambora beats. Caetano Veloso, the venerated Brazilian songwriter who helped start the Tropicalia movement, was given the Latin Grammy Person of the Year Award on Wednesday. He appeared during the show to croon two smooth jazzy numbers -- "Capullito de Aleli" and "Odara" -- with Mr. Sandoval, the trumpeter, providing a soaring solo. Electronic music was well represented in the show, a reflection of that genre's growing popularity. 3Ball MTY was joined by America Sierra, El Bebeto and LMFAO's Sky Blu for a medley of dance-pop. The show ended with club music, as Pitbull,the Dominican vocalist Sensato and a Spanish DJ, Sak Noel, did a version of Pitbull's hit "Crazy People," while female dancers in costumes meant to resemble strait-jackets danced around them and hit one another with pillows until the air was filled with feathers.
