Nominations expanded in key categories as Latin Grammys return to Las Vegas.

The 13th edition of the Latin Grammy Awards returns to Las Vegas this year and will air live from the Mandalay Bay Resort & Casino on Univision on Nov. 15.

The Spanish-language broadcast -- which will air 8 p.m.-11 p.m. ET/PT (7 p.m. CT) -- is one of TV's most-watched nights and features some of the biggest names in Latin music.

The awards show, and events that take place during the week, are a partnership among the Latin Recording Academy, Univision, the Mandalay Bay Events Center and the Las Vegas Convention and Visitors Authority.

This year the Latin Recording Academy has included five additional spots in each of the four major categories: record, album and song of the year and best new artist. This special feature will highlight the nominees in the latter two categories.

Some highlights of this year's musical achievements include Dominican Republic-born Juan Luis Guerra, a prolific singer/songwriter/producer who leads with six nominations including record of the year, and composer/singer/songwriter/guitarist Caetano Veloso from Brazil, who will be honored as Person of the Year during a special Latin Grammy celebration.

Lifetime achievement honors will be presented to Spanish-born singer/ songwriter/composer Luz Casal, Argentine singer/songwriter/actor Leo Dan, Puerto Rican-born singer/dancer/actress Rita Moreno, Brazilian singer/songwriter Milton Nascimento, singer/actress/TV host Daniela Romo, Latin jazz bandleader/salsa singer Poncho Sanchez and Brazilian singer/guitarist Toquinho.

The trustees will give a special award to flamenco guitarist Juan Carmona "Habichuela" and Puerto Rican-born Yomo Toro, known as "the King of the Cuatro."

The awards process this year received more than 7,500 submissions in 12 months-a record-during the eligibility period from July 1, 2011, to June 30, 2012. For the first time, the Latin Recording Academy and music streaming service Spotify are working in tandem to offer voting members and music fans access to the music of those nominated.

The Latin Recording Academy is an international, membership-based group of Spanish- and Portuguese-speaking recording artists, musicians, songwriters, producers and other creative and technical recording professionals. Its mission is to improve the quality of life and cultural condition of Latin music and its makers.
