T.I. says he and Dr. Dre have created “chemistry” together on their latest collaboration.

The ‘Sleazy 2.0’ rapper has teamed up with the legendary producer for his forthcoming mix tape ‘F**k da City Up’ and he says they worked very well in the studio together.

He told MTV News: “Dre was here. He sent for me over to the spot. We really just turned up more than anything else. It was about creating chemistry.

“Of course we can get together, he got hot beats and I got dope rhymes, so we can always get together and make music. But for people to feel what we’re sayin’ and for it to sound like a party comin’ through your speakers, you gonna have to create some chemistry. So that’s what we spent more time doin’ than anything else; developing that chemistry.”

This is not the first time the pair have worked together.

A few years ago they recorded ‘Topless’, a song which was said to be included for Dre’s often delayed album ‘Detox’ but it was leaked onto the internet.
