At 8 p.m. tonight, the White House website will live-stream a concert from the East Room, featuring major musical performers and top-drawer celebs. The Black History Month concert, a tribute to America's civil rights movement, was scheduled for later this week but moved up to this evening because of the impending snow storm.

Here's the lineup, according to the White House (it wouldn't be a shock if some performers don't appear, since they weren't originally supposed to be in Washington today).

They are, in alphabetical order: Yolanda Adams, Joan Baez, Natalie Cole, Bob Dylan, Jennifer Hudson, John Legend, John Mellencamp, Smokey Robinson, Seal, the Blind Boys of Alabama, the Howard University Choir, and The Freedom Singers, featuring Dr. Bernice Johnson Reagon, Rutha Harris, Charles Neblett and Toshi Reagon.

Guest speakers include Robert De Niro, Morgan Freeman and Queen Latifah. President Barack Obama is the emcee.

The show will feature songs from the Civil Rights Movement and readings from Civil Rights speeches and writings.

Those who aren't in-the-know online here at Maryland Politics will be forced to wait until Thursday, when the program is televised at 8:00 p.m. on public broadcasting stations as part of the "In Performance at the White House" series.

In addition, NPR will produce a one-hour concert special from the event for broadcast nationwide on NPR Member stations throughout the month of February, beginning February 12th. The special will be available on www.npr.org/music.
