Cuban Song

hey
i was wondering if any of you can help
i just came back from varadero, cuba and i heard a song that i want to find.
i do not know much about it!
its a really long song, maybe 10 mins long they would play it at the beach at my hotel.
the beginning is weird, it sounds a bit african, and during the song "chango" is mentioned a lot.
anyone know what it might be?
thanks!

A long shot, but ...

Artist: Ozomatli
Title: Chango
