Kanye West took aim at U.S. Recording Academy officials for his Album of the Year Grammy snub at a show in Arizona on Tuesday (10Dec13), suggesting the oversight is racially charged.

The outspoken rapper halted his show in Phoenix to share his disappointment with fans after Yeezus failed to grab a nod in the top album category when the nominations were announced last week (06Dec13).

He raged, "I'm 36-years old and I have 21 Grammys. That's the most Grammys of any 36 year old. Out of all of those 21 Grammys, I've never won a Grammy against a white artist. So when the Grammy nominations come out, and Yeezus is the top one or two album on every single list (poll of the year), but only gets two nominations from the Grammys, what are they trying to say? Do they think that I wouldn't notice?

"Do they think that, someway, that I don't have the power to completely diminish all of their credibility at this moment?

"When you see me talking about what people are doing when I say 'marginalised', when I say 'boxed in', when I say 'hold back' (sic), when I say 'people are afraid of the truth', that's one example right there in front of you."

West admits he's not impressed with his two Grammy nods for Best Rap Album and Best Rap Song for New Slaves, adding, "People come to me and congratulate me on those two nominations. F**k those nominations!"
