His flow is very nasally, with a rambling but on tempo speed. Either you like him or you hate him, he's something of an aquired taste.
The frontman of the best rap group ever, Cypress Hill. B is known for having a high pitched voice which contrasts fellow CH rapper Sen Dog's deep aggressive voice. His flows are solid and he can rap circles around 99.9% of these "mtv gangstas" you see today. In addition, he was shot in his youth, but didn't use it as a marketing tool like 50 Cent did. He lived with, and likely banged Carmen Elektra, and has released solo albums called "Gunslinger" volumes 1 and 2.
To top it all off, he's a professional toker, smokin' that smelly northern Cali, and is known for being a supporter of marijuana legalization.
