That's the Evolution Control Committee Public Enemy - Herb Alpert mash-up thingee mentioned in that article in the previous entry, which you can download from the preceeding link.
What does Chuck D. have to say about this?
Stay Free!: As you probably know, some music fans are now sampling and mashing together two or more songs and trading the results online. There's one track by Evolution Control Committee that uses a Herb Alpert instrumental as the backing track for your "By the Time I Get to Arizona." It sounds like you're rapping over a Herb Alpert and the Tijuana Brass song. How do you feel about other people remixing your tracks without permission?
Chuck D: I think my feelings are obvious. I think it's great.
Herb Alpert could not be reached for comment.
Ok, I didn't try.

Yes. The Rhythm The Rebel.
The Rebel Without a Pause track is no joke. I should probably download the entire album, huh?
Yeah, I think so.
They did a really nice job of "lo-fi"-ing the vocals so that they mesh well with the old tracks.
When it comes to Public Enemy mash-ups, I'm pretty fond of this one...
(Longer version can be found here!)
Jason, still haven't listened to all the tracks. And should dig a bit deeper looking for E.E.C.'s cover of "I Still Havent Found What I'm Looking For." That was cool. And yeah, they did do a good job with the vocals. And the horns.
Wendy, those make me happy. Thanks.
