Rīgas Mūzikas Festivāls - Latvian NS for NVSC #29

Did you make that NS title like that intentionally? I mean, the one part that's supposedly latvian? And can you tell me, how did you get it to look like this? Because I know it can't be Google Translator...

There are no problems with diacritics in this case, so you don't need to worry about that.
Does your idea behind those words is "Riga Music Festival" (just in latvian obvs)? If so, then you should've just translated it with Google Translate, because that would give you correct translation. Even if it's in genitive (only first 2 words need to be in genitive)
The reason, why I asked you about this is, because there's something big missing, that non-latvians usually relate us to. They say (and mostly are surprised), that we are obsessed with words that end with letter "s". That's the big thing you're missing here - all of those 3 words need a letter "s" at the end of them. Other than that they are fine. Right now those words are in nominative... I mean, the first 2 are. The last word is just missing "s" to actually be called a word.

Festivāl without "s" at the end of it would be correctly used in 2 cases:
1. When you call out someone (for example, "Hey, Jake!") - then it would be "Hei, festivāl!" (in latvian)
2. a surprised expression, which is followed by question mark (for example, "Really?") - then it would be "festivāl?" (in latvian)

I hope I explained clearly enough. If you ever have any trouble with latvian language, you can always ask one of us few latvians that are around here
