Wale dropped his debut album in 2009 on Interscope. Wale had a massive push. Kendrick - had a massive push. J. Cole has had a massive push. My point is, these artists are getting the big pushes because the labels know that these are now the artists that have the most potential to sell albums.
There's not a gangsta rapper in his 20's with a Gold album plaque.
Like I said - Jeezy and Ross pre-date Graduation. They received the big pushes earlier and garnered a lot of fans that have stayed loyal. They are also the biggest artists of that type. Nobody else you mentioned has a gold album.
Point is, J. Cole and Kendrick aren't breaking the mould. They are billed as the premier acts on their labels and they've had a lot of marketing dollars behind them. I love K.Dot's music but he was pushed so hard by the industry. Jay-Z had Beanie as the premier act on Rocafella (other than himself), that type of act sold the most albums at that time (DMX for example). Jay-Z has J.Cole as the premier act RocNation, that type of artist pushes the most albums (Drake for example)
I got ya and I agree with you for the most part, but I wasn't even referring to gangster rap (more gucci/waka/molly ignorant shyt like that), or saying that they broke the mold, just that they currently, in my opinion, are the 2 ushering back in real hip-hop in terms of lyricism and just that old school vibe all around. Wale I look at as being in the mold of Kanye and Lupe like you said, but Cole and Kendrick I look at as more of a hybrid between backpack rap mixed with a little gangster rap influence (style/technique more so than content). Also, to me they've both (Kendrick certainly has) had a bigger impact on hip-hop than Wale.
But I agree that Kanye helped usher in this era of hip-hop and made it possible for these 2 artists to be in the position they are in, to even be able to make an impact on the game and be the face of what is hopefully a new era of hip-hop music, or at least open up a lane in the mainstream for the real shyt to flourish and sell, which GKMC and Born Sinner would seem to confirm that to be true.
