Don't ever critique Kanye West.
Veteran Canadian music producer Bob Ezrin is feeling West's wrath after he published a review of the rapper's latest album, "The Life of Pablo," in Bob Lefsetz newsletter. West turned to Twitter late Tuesday night to fire back at Ezrin – and then some.
"Has anybody ever heard of Bob Ezrin???" he began his rant. "What the f--k does he know about rap..."
The "Famous" artist didn't like what Ezrin (who has worked with Kiss, Pink Floyd, Lou Reed and Peter Gabriel) had to say, which complimented West's work as a rapper but also claimed he wasn't quite at the level of Kendrick Lamar, Macklemore, Tupac or Jay Z. Ezrin also criticized West's skills in the field of production, saying he isn't at Timbaland's level. None of this, obviously, sat well with Kim Kardashian's husband.
"I'm tired of old people that have no connection with anything trying to comment on music!" he continued. "Do something relevant... Please don't speak on me bro ever again!!!"
But he didn't stop there; West then involved Ezrin's children. The last time West brought up kids in a Twitter rant (involving Amber Rose), it didn't go so well, and he promised never to talk about them again. That didn't last...
"Your kids are ashamed of their dad... Sorry for speaking about kids...but could you imagine if you were Bob Ezrin's kids...," he mused. "I'm so sorry for them...I will send them free Yeezys to make up for the embarrassment that you have caused your family!"
At least they'll be getting free shoes.
Let's be honest, though. This wouldn't be a West diatribe if there weren't a jab taken at Taylor Swift, his longtime frenemy. While tooting his own horn about the past albums he has released, West couldn't help but bring down Swift in the process.
"I made Dark Fantasy and Watch the Throne in one year and wasn't nominated for either and you know who has 2 albums of the year," he tweeted.
Swift probably isn't sweating it though, as she got her jab in for his "Famous" lyrics during the 2016 Grammys when she accepted her trophy for Album of the Year. "And as the first woman to win Album of the Year at the Grammys twice, I want to say to all the young women out there, there are going to be people along the way who will try to undercut your success or take credit for your accomplishments or your fame.
"But if you just focus on the work and you don't let those people sidetrack you, someday, when you get where you are going, you will look around and you will know that it was you and the people who love you who put you there. And that will be the greatest feeling in the world. Thank you for this moment."
