MONUMENTS: The Pentagon Memorial opens to the public for the first time tonight at 7 p.m. It will be open 24 hours a day thereafter, but plenty of people will be heading down tonight to see it for themselves on the anniversary of the Sept. 11 attacks. The Navy Band and the Sea Chanters Chorus will perform a musical tribute to mark the opening from 7 p.m. to 9 p.m. Don’t forget about the bus route changes, and be prepared for large crowds on the Metro.

MUSIC: The Eighteenth Street Lounge hosts jazz trained keyboardist Leo Tardin and his live electro-funk ensemble Grand Pianoramax, along with DJ Spinna, who lent his considerable talent to some tracks on the latest Pianoramax album, The Hook (Remixes). The ESL show kicks off at 9:30, but the whole group will also be at DJ Hut from 5 to 6 p.m. for a free live show.

MUSIC: Baltimore’s Thank You are starting to make waves with their rhythmically disorienting take on punk rock (fans of D.C.’s late, great Black Eyes will want to take notice). Catch them at DC9 with local act The Differents. $8, 9 p.m.

READING: Local D.C. author Louis Bayard makes an appearance at the Olsson’s in Dupont Circle to discuss The Black Tower, his latest novel, a detective story set in 1811 Paris. 7 p.m.

MOVIE: The DC Shorts film festival kicks off tonight with four different short film programs at the Landmark E Street Cinemas, and an opening night party at 9:30 p.m. on the roof deck at Carroll Square. A note on the web site says that individual screening tickets, which cost $12, should be bought through the Landmark web site until further notice, as the festival’s online ticketing function is apparently experiencing some glitches.
