Of course the Queen of Latin Music must be there: Shakira for ever! She is the greatest of all time that's why she deserves always the first place when it comes to Latin industry!
Ah!!! while I love pretty most of these performances, I'm so so so happy Juan Gabriel made the spot it did. Such an ICON such a voice. Hearing him sing some of his songs gives me chills just on how powerful they are.
The absolute best performance of ANY Grammy show (English or Spanish) I've ever watched was Calle 13's 2007's interpretation of "Pal Norte" in Las Vegas. I've been trying to find the whole video of the performance (including the opening act by Orishas) in HD, but I have come up short.
Technically, the term Latin comes from Italy/the Latin region (Italy, France, Spain, Portugal.) I have no idea why we call ourselves 'Latino' in the Americas because it makes no sense.
