Festival International why should I go?

because it's FREE admission, great food options at the Festival or around town, weather is often perfect, solid music lineup on 5 stages x 4 days, the downtown area is easily walkable, and the stages are only 1-2 city blocks apart.

It kinda reminds me of City Stages that use to be held in B'ham in the early 90's - family friendly atmosphere

It is a fun and interesting way to pass a good time.

It's worth going, not only is it free but I'm always impressed by how modestly priced drinks/food is for a free festival, domestic beers are like $3.50, craft beers $5-$6, mixed drinks are like $6. Those are damn good prices.

Walk around, listen to some music you've never heard, eat and drink well, check out the artwork, etc. Try to catch a show at Blue Moon Saloon, occasionally some of the bigger acts will drop in and do a jam session.

Festival Acadien et Creoles in October is another great one worth checking out, basically Festival International but with a focus just on Cajun/Zydeco/Creole music. It's smaller, and at Girard Park, but also free, also great prices on food/drinks, etc.

Everyone pretty much covered it already. I live DT Lafayette, so I am pretty biased.

Might still be a few cool spots to rent out that are within walking distance.

Do it.

Yes. Nothing like some German or Brazilian kitty.
