If you haven't heard the hip hop Newgrounds yet you're missing out! tingtonger or "Big Red" has organized NG's very own competition to showcase the sick talent it has.
Check out the official thread for it here:
NG Hip Hop Competition '10
In here you can find info on the Sample Battle, a hip hop crew Battle for Newgrounds, MC's and producers tag teaming to create tracks in the Time Trial, and more! If you make or dig hip hop music get 'yo ass into that thread!
NGHH MC Knock Out
20 Newgrounds MC's will be pitted against each other in a ferocious battle of tongues. :) Really though, MC's will be given beats to spit venom over and at the end of the day... THERE CAN BE ONLY ONE!
NGHH Art Competition
In the end winning submissions will be showcased in a flash, which will need some gangsta art to make it look less boring. The theme is 80's hip hop, so think maaad bling and Will Smith wearing pink and green!
So, read through the threads, review the tracks submitted, and get yo'self into the competition! Rules are all posted in the threads! There will be prizes in the end and you get cyber-respect from all NG-thugs for even participating!

To promote the contest Newground hip-hop-hap-heepers have been posting freestyles! So listen to the ones already posted, and if you think you can rhyme then drop your own verse to hype the NG competition!
