West Coast early 90's? - Dr Dre & DJ Quik
East Coast mid 90's? - DJ Premier & Pete Rock & all of the D.I.T.C. producers

east coast new millenium-el-p,just blaze,kanye,heatmakerz,stoupe
west coast early 90s-dr.dre and dj muggs
east coast mid 90s-havoc,beatminerz,DITC.
dont give a fuck about the other 2.

Man, I'm truly sick of all these East Coast, West Coast, South shit. Instead of best regional producers, lets do best producers of each medium:

Live Instruments: ?uestlove (The Roots)

Digital + Live: Mike Shinoda (Fort Minor/Linkin Park)

Turntable & Software Only: 9th Wonder

Hardware Only: DJ Premier / Pete Rock

Sample Only: Ant / RJD2 / Kno

Sample & Digital: Just Blaze

There are plenty more very, very talented producers, I just feel these guys really revolutionize music production in their fields.

whats hardware only

East Coast new millenium? Just Blaze
West Coast new millenium? Dr. Dre
West Coast early 90's? DJ Muggs
East Coast mid 90's? DJ Premier & The RZA
Crunk shit now? Lil Jon

East Coast new millenium? Probably just blaze
West Coast early 90's? Dre, Muggs
East Coast mid 90's? Primo, RZA
Crunk shit now? WHO
Trap Music? CARES

http://www.soundclick.com/yme216 just listen to those tracks that he's free stylin over...Dj Premier no ?

whats hardware only

Hardware as opposed to software....MPC opposed to Fruity Loops...Analog/Digital Recoder opposed to Digital Software....

Crunk/Southern - DJ Paul And Juicy J (The most underrated southern producers imo)
East Coast - Just Blaze, Heatmakers, 9th Wonder, Pete Rock
Midwest - Kanye West, Soundtrakk, Don Juan,
West Coast - EA SKI, Tron Treez, Rick Rock

yeah, DJ paul and Juicy J are defenitley the best in the south.

The Crunk shit is Lil 'Jon.
