Kanye West Screaming, Mic Throwing Raises Concerns After Bizarre Rant (VIDEO)

Kanye West wrapped up his second show in London at Hammersmith Apollo on Sunday and his bizarre behavior has sparked fears for his well-being.

The rapper, who lashed out during his first show on Saturday, began screaming excessively after performing his 2006 hit "Touch The Sky." His screams were followed by the slamming of his microphone before he abruptly exited the stage.

Just one day prior West, 35, went on a bizarre rant while performing before fans and lashed out at the Grammys and "business people."

"I hate business people. People get on the phone with me and they're like 'what's the numbers at? How much did you sell? How much shampoo did you sell with your face on it?" West said to roaring applause.

"Since when was making music about getting rich?" he continued before taking a jab at the Grammys "Grammy's can s--- my d---."

It appeared that no-one was off limits during West's tirade, as the rapper even took aim at his best friend Shawn "Jay-Z" Carter, who recently collaborated on a song with Justin Timberlake. The song "Suit & Tie" is a mixture of old school R&B and soul, but West made it clear that he is not impressed.

"I got love for Hov but I ain't f------ with that 'Suit and Tie,'" West said, later adding, "We're all gonna die one day, so I'ma live my life my way."

While West is no stranger to inappropriate outbursts, with his most infamous occurring at the 2009 MTV awards, fans are growing concerned over his increasingly strange antics. Critics took to social networking site Twitter to weigh in on the rapper's performances.

"Kanye West going through some pain in this Video. sounded like a cry for help," one user tweeted.

"I think he's actually losing it! Is Kanye on something? Why is he yelling and throwing his mic? What a psycho! #gethelp," another tweeted.

"Wtf is wrong with Kanye West? Lol that mf is crazy. Literally!" What happened? LOL," one concerned fan wrote.
