The Stronger hitmaker recently gave an interview to BBC Radio 1's Zane Lowe and made several lofty claims including calling himself "the number one rock star on the planet" and promising to found the first trillion dollar company.
Now British rocker Astbury has spoken out to blast the rapper's comments and mock his performance style.
He tells the London Evening Standard, "If you look at David Bowie you never read an interview where he talks about what he's going to do. He just does it. I've seen that guy (West) perform - he just stands still. Get your hands off the trophy until you've earned it.
"It's not about the accolades - you're a service. You're not about your accoutrements - your legacy is being a service... A lot of these successful stars now, once their helicopter has left they pull the ladder up. It's the idea of coveting knowledge. That's bulls**t - spread it around."
