A güiro is a notched gourd you scrape with a stick. It's also the name of a style of religious music played with a güiro accompanied by other traditional instruments. I don't know what pa' means but this appears to be a Cuban Santeria güiro toward an altar of Changó, for Changó's benefit, Changó being the sky god.
If you don't like it, it doesn't matter. It's not for you. It's for Changó. No, seriously, you'll like it. It builds.
