Big Sean

If the guest appearances on his three mix tapes are any indication, Big Sean will be a popular rapper shortly. He’s already earned street cred performing with famous rappers like Kanye West, Drake, Chris Brown, Wiz Khalifa and Wale. His debut album, tentatively titled Finally Famous, and rumored to be out later this year, will likely produce similar high-profile collaborations, but its release has been continually delayed. Though he focuses on rags-to-riches clichés—rapping about partying, clothes and money—his wordplay is witty and beats are bangin’. Check him out before he becomes really famous. 5640 Dudley Boulevard, http://uknowbigsean.com.
