Yep, a lot of people don't know that Biggie messed with Dilla before his Death. The song was originally called "The Ugliest" or "Brooklyn Lockness" but was later changed to "Dangerous Emcees" with a different beat on "Born Again". The original beat was then to be sold to Busta and called "Modern Day Gangsters" but the song wasn't completed outside of Big's verse. Biggie wanted the song to feature Busta and NaS. Biggie's verse is actually a Pac diss. It's filled with a ton of subliminals. The beat was fire and Biggie sounded dope on Dilla's production, Well Big sounded dope over everyone's production but it seemed like a good match with Big and Dilla. Here's the beat and song:
Yeah, ninety-six, for my Nordstrom Ave nikkaz
My Fulton Street nikkaz (hardcore for ninety-six)
Dangerous MC's..
Uhh (check it out) uhh
Diamonds on my neck, chrome drop-top
Chillin on the scene, smokin pounds of green
Oooh-wee, you see, the ugliest
Money-hungriest, Brooklyn Loch Ness
Nine millimeter cock test, wan fi' test?
And the winner is? Not that Thinner Kid, Bandana Tatoos,
my fist never bruise. Land-still-cruise, Frank White paid his dues
Ask who's the raw, bet they say Poppa very
Look forward to me like commissary
All of a sudden, now every-body Big Willie
Done did it, come widdit, get yo' head splitted
or get your neck slitted, admit it, you overdid it
Your shyt it, just ain't got that LOUD
Gold tooth shine like TA-DOW!
Biggie Smalls the illest and how, frays raise your eyebrow
By now you figure, he talkin bout that nikka
but your weak-ass assumptions, lead led to dumpin
IV to pump-in, you're feeling something
Catch my drift, or catch my four-fifth lift
at least six inches, above project fences
Turn meat to minces, jokes turn to flinches
When I rain I drenches, cleared your park benches
Missed you by pinches your talk is senseless
Actor needs chiropractor for cracked jaw
Yes I rocked your cheddar box
Dangerous you're not I gets down
Twist your body {*singing*} round and round, upside down
All the underlined are Pac refereces/diss. He even ends the verse singing like Pac did on "I get around". Here's a Dilla "Kick in the Door" remix/mashup that Premo co-signed.
