What ever happened 2 Rap groups and Crews

There was a time when rappers used 2 have groups and crews and when you saw them perform it was more than just 1 guy walking back and forth on stage. Now dont me wrong there has always been great solo artist but it seems that the rap crews are dead now, the last relevant rap crew would probably be the Wutang clan but since then no other real crew has emerged. There used to be some great duos such as Run Dmc, EPMD, Nice and Smooth, Black Sheep and Kid n Play then there were the hot groups Sugar Hill Gang, Whoudini, Naughty by Nature, De la soul, LODS, Three Times Dope, Lords of the Underground, Furious Five, and Treacherous Three just to name a few. Then there were the crews such as Juice Crew, Flavor Unit, Hilltop Hustlers, Flipmode, Hit Squad, Bomb Squad and Rush Mngmnt. We are so caught up in the almighty dollar that we no longer want to share that we have lost touch with the inner beginnings of hip hop what started out fun is now simply "business". Id love to see what some of there artist could do if they pooled their resources and worked together creatively then maybe it wouldnt be so easy 4 just one or two artist to easily monopolize the industry there is strength in numbers so get together lets make hip hop what is was meant to be a culture and not just a cash cow...Chaos
