I own all of Lewis Black's DVDs and CDs, and I am also a big fan of his material on The Daily Show. That said, this is definitely his best CD that he's done.
First, I will have to rebut some of the reviews here -- this is not recycled material. Yes, there are a couple of Superbowl jokes that were reused from The End of the Universe and his 2002 Comedy Central Presents special, and yes, his "civics books" joke was reused from Rules of Enragement. However, those jokes have been far more refined in this performance and are better versions. The rest of the material is original, and of all his performances, he seems to blend with this crowd the best.
Also, the first 8 tracks (with the exception of Gay Marriage) deal with Superbowl Halftime 2004, and nowhere will you find any of this on any of his other CDs or DVDs. The thing with his other CDs is that if you have all h is material, you'll see it all recycled. The White Album is like his 1998 and 2000 Comedy Central specials. The End of the Universe is like his 2002 special. Rules of Enragement is like Black on Broadway, and Carnegie Hall is like Red White and Screwed. You'll find a lot of new material on all of this, yes, but a significant chunk of the pairs I put up have similar jokes in each. Not so with Luther Burbank. This is the only CD of his that I laughed the whole way through, since I rarely ever stopped and thought, "Wait, I've heard this before." If you've seen all he's done on TV, you will barely recognize any of the material on here.
His jokes are hysterical. While he sometimes, though rarely, misses the mark on some of his other merchandise (the latter half of Red White and Screwed is a good example of this), he never seems to miss a beat here, constantly churning out wit like it was nobody's business.
This is a must-buy. If you are diving into his works and want a CD of his, this should be the first one you get.
