It's a rainy Saturday in Brooklyn, but thousands are patiently waiting for transportation to a free concert, emceed and hosted by Dave Chappelle. They don't know what performers are in store for them until they get to the concert location, but if they did, they might be a little less patient.

Chappelle has the means to put on the concert that he's wanted to see his entire life, and nothing stops him from securing Kanye West, Mos Def, Talib Kweli, Erykah Badu and the Roots to play. He even achieves the seemingly impossible: He reunites the Fugees for its first performance in over seven years.

To make the day unforgettable, he enlists the White Stripes and Bjork music video director extraordinaire Michel Gondry (also of award winning "Eternal Sunshine of the Spotless Mind" fame). Gondry, along with his prized cinematographer Ellen Kuras, will be catching all of the action behind and in front of the stage.

In a film with big names and big expectations, Chappelle's comedy stays just as funny as on his show, though not as sketch based. Fans of the "Chappelle Show" may not enjoy the movie since it focuses on long musical interludes.

But even casual music fans shouldn't get bored during these parts because the clips that made the final cut are the artists' more popular songs. The top-notch performances don't hurt either. West performs "Jesus Walks" with the help of Ohio Central State University's marching band — a powerful, choreographed moment that translates almost better to film.

Kweli, with the help of West, adds his hip-hop hit "Get By," and the Fugees (of course) perform "Killing Me Softly with His Song," off the best selling hip-hop record of all time.

Chappelle also can't help noting the symbiotic relationship between musicians and comedians. This leads to one of the funnier lines in the movie: "I'm mediocre at both and yet have managed to talk my way into a fortune."

Though framed with comedy, important political, socioeconomic and music issues surfaced through the day.

Wyclef Jean asks some of the students in the marching band what they would do if they were president, and it seems as if they have never been asked that question. The concert is held in an area of Brooklyn that Biggie Smalls and all of his friends grew up in. When Chappelle visits the daycare Biggie attended, it is one of the more touching, yet comedic, scenes of the film.

Another neighbor of the concert is a possibly insane, well-intentioned, older, bohemian couple who think rap music sends the wrong messages, but they tolerate the block party for the day. Gondry immediately transitions to an artist singing about how it's taboo to rap about God.

The clusters of people who left during the long musical portions of the film were probably the ones who needed to hear these important, but not preachy, messages the most.

Gondry fans looking for his surrealistic touch will not find it. Instead, he draws from his music video experience and pairs his dead-on timing of shot changes with the flow of the music. He also seamlessly transitions between the songs and the documentary portion.

Though edited, Chappelle seems like he's always "on," when he needs to be, and shows a more improvisational side of himself. The music follows suit and shows its staying power, social relevance and importance.
