Proving once again that D.C. has a rich, often-unheard musical history, Maryland Public Television will air a new documentary on The Bayou, a former jazz club/music hall on the K Street waterfront.

Years ago, the Bayou was the city’s penultimate live music venue. We are talking pre-9:30 Club era. The Bayou: D.C.’s Killer Joint, sheds light on the fabled Georgetown music hall and its high-profile clientele.

The documentary delves into the club’s history of decadence and debauchery, including an infamous gangland assassination. The Bayou was frequented by the likes of Micky Mantle and the Kennedy brothers. A little Irish band called U2 made its state-side debut there as an opening act, many years before selling out football stadiums nationwide. It was exactly what is now missing in the watered-down streets Georgetown.

The Bayou: D.C.’s Killer Joint will air February 25 on Maryland Public Television (Check local listings).
