This is the record that pretty much kicked off the whole 'bastard pop' genre - where a clever bootlegger would fuse the vocal track of one song with the backing of another. Here we have Public Enemy and Herb Alpert (Bittersweet Samba, from Whipped Cream...).
The reason this record (unlike most of the other mash-ups) works so well is that it sounds like a genuine collaboration - the parps of the Tijuana Brass and Chuck D's rap spits meld perfectly. It's a smart-arse idea that becomes a work of art.
