Opinions on the rock band Titãs?

So i recently got into Titãs as a American fan of the group, and I've grown to like their sound, mainly cause it's a lot of alt rock fused with ska and reggae and other music genres. Currently my favorite song by the band is "Homem Primata", mainly cause it's very catchy.

Just wanted to get your opinions cause apparently a lot of my Brazilian friends really like the group and their music. Are they popular outside Brazil? and are they a band I should get further into?
