Rapper Kanye West has lashed out at music producer and keyboardist Bob Ezrin on Twitter.

Kanye West has just taken aim at a brand new target - this time music producer and keyboardist Bob Ezrin.

The rapper was responding to Ezrin's scathing critique where he said Kanye isn't on the creative level of some other artists such as Jay Z, Tupac, Biggie or M.C. Hammer.

"Instead Kanye's greatest achievements have been in the form of excessive behaviour, egomaniacal tantrums and tasteless grandstanding," he wrote.

Taking to Twitter on Tuesday, West unleashed a furious rant where he took aim at his children and told him to "never speak in public again".

`Has anybody ever heard of Bob Ezrin?` West wrote.

`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! Your kids are ashamed of their dad," he added.
