the concert Dave always wanted to see

I cannot recommend Dave Chappelle's Block Party highly enough. It is wall to wall fun, with enough social subtext to give it all some bite and some grounding. The bite is more piercing if you know the present context in which the film emerges.

Here is a not-quite-arbitrary timeline:

• January 2003: Wattstax, the restored edition, is revived at Sundance.
• September 7, 2004: The Wattstax Special Edition DVD is released.
• September 18, 2004: Dave throws his block party.
  
• March 2006: After a lot of water passes under the (Brooklyn?) bridge, the rest of the world gets to join the party.

Owen Glieberman's review in Entertainment Weekly totally nails this one. Favourite quotes:

"...he exists in a perpetual limbo of satirical detachment, but only because he appears to be deviously fascinated by every person and situation he encounters. Like Richard Pryor, he's all feelers, with a mockery that flows, almost compulsively, out of his screwy generosity of spirit."

"Dave Chappelle's Block Party is perhaps the first concert movie since Stop Making Sense to give you a blissful buzz. The buzz comes from the music, which has a loose, burning joy that's rare to behold in a live rap performance, and also from Chappelle's wicked prankster's glee, which spreads through the movie like a happy virus."

"...the finale, in which Lauryn Hill, with her china-doll face and luscious tremolo, reunites with the Fugees to do ''Killing Me Softly With His Song,'' is sublime..."
