The 9:30 Club (officially known as Nightclub 9:30) is a nightclub and concert venue in Washington, D.C. It is located at the intersections of 9th Street, V Street, and Vermont Avenue in Northwest DC and is served by the U St/African-Amer Civil War Memorial/Cardozo stop on the Washington Metro. Many bands, both big and small, have played at the 9:30 Club and it is still in use to this day.
The club's name is derived from its original street address, 930 F St, NW, even though it has since moved to a larger venue at 815 V St, NW. The name refers to the original opening time of 9:30 pm and early advertising on D.C.'s WHFS radio featured the catchy motto: "9:30 - a Place in Time!"
Since the early 1980s, the 9:30 Club has been known as a progressive venue noted for its talent in discovering up-and-coming acts. Most famous for using the old 9:30 Club is the hardcore punk crowd based around Dischord Records and then-local bands such as Minor Threat and Government Issue.
The original venue was also noted for its distinctive odor. Hence, its popular nick-name: "The Dirty 30."
Tiny Desk Unit was the first and last band to play the old 9:30 Club (although The Fleshtones from New York were the first band to be booked.)
