I'm not surprised to learn that Dirty Country won the SXSW audience award in the "24 Beats Per Second" category. I have rarely heard people laugh so much at a documentary -- and not just giggles but full-blown belly laughs. Dirty Country explores a musical genre that I hardly knew existed: songs that contain lyrics that the FCC would never allow to be broadcast due to their sexually explicit nature. While the film focuses on one country-music artist who delights in dirty lyrics, we also are exposed to dirty cabaret, rap, indie rock and blues music. This is not a movie for children or the easily offended.
