After a few days away, Kanye West is back on Twitter.

And he had some scores to settle. The first was with producer Bob Ezrin.

The 66 year old is known for his work with Pink Floyd, Alice Cooper, Lou Reed, Phish and Kiss. But this week he is known for a scathing article he wrote about Kanye West. In it, he acknowledged that 'Ye has talent, but not nearly as much as he thinks he does.

"Unlike other creators in his genre like Jay-Z, Tupac, Biggie or even M.C. Hammer for that matter, it’s unlikely that we’ll be quoting too many of Kanye’s songs 20 years from now,” Ezrin writes. "He didn’t open up new avenues of public discourse like NWA, or introduce the world to a new art form like Grandmaster Flash, or even meaningfully and memorably address social issues through his music like Marshall, Macklemore and Kendrick."

Of course 'Ye would have something to say about this:

Has anybody ever heard of Bob Ezrin???

What the fuck does he know about rap… — KANYE WEST (@kanyewest) February 24, 2016

I’m tired of old people that have no connection with anything trying to comment on music!

Do something relevant… Please don’t speak on me bro ever again!!! — KANYE WEST (@kanyewest) February 24, 2016

Your kids are ashamed of their dad… Sorry for speaking about kids… but could you imagine if you were Bob Ezrin’s kids…

I’m so sorry for them… I will send them free Yeezys to make up for the embarrassment that you have caused your family! — KANYE WEST (@kanyewest) February 24, 2016

Bro you said Macklemore was more important musically than me… no offense to Macklemore, he’s a nice human being!

Bob please never speak in public again… you are everything that is wrong with the old guard … — KANYE WEST (@kanyewest) February 24, 2016

it’s guys like you that run companies and don’t invest in Ye even if I’m your kid’s idol!!!

For their part, both Bob Ezrin and his grandaughter (his kids are older than Kanye, and probably don't want Yeezys) are having fun with 'Ye's rant on their Twitter pages.

But Kanye wasn't done. He also took another shot at his mean girl rival.

Rock and Roll was stolen… Rap was exploited… — KANYE WEST (@kanyewest) February 24, 2016

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.

Of course we know who. She's tall and skinny. But we're not sure how cool her pants are.
