You did a fine job of setting up "En la ciudad": providing enough background so I knew what to listen for, but at the same time leaving room for surprise and discovery. Andrea Echeverri is something else! I've bookmarked your Catalan page and look forward to exploring that music.
Speaking of musical orgasms, here's a collaboration that will leave you reaching for a cigarette, even if you don't smoke. The gender roles from "En la ciudad" are reversed, with Roberta Sa in a traditional female role and Ney Matogrosso known for subverting gender expectations in his live performances (though he's conventionally dressed here).
