Slog tipper Brian has informed me that the White House will host its first-ever Poetry Slam tonight. (Although there's a bit of confusion about it: This site calls it a "poetry jam.")
The White House Poetry Slam will feature: James Earl Jones, Michael Chabon, Ayelet Waldeman, Jazz pianist ELEW, poet Mayda Del Valle and playwright Lin-Manuel Miranda.
I think James Earl Jones should automatically win every single poetry slam he enters, by virtue of being James Earl Jones. In any case, You should be able to livestream the get-down Jammy Slam from the White House's website starting at 4:45 pm, Seattle time.
