Jeezy/Tee Grizzley

Rapper Jeezy worked a few key collaborations into the mix for his latest album, last year's Pressure. He teams up with Puff Daddy on “Bottles Up” featuring Puff Daddy and recruits Tee Grizzley for “Cold Summer." Not to be outdone, Tee Grizzley, who opens tonight's show, delivered a huge hit last year with Moments, an album that features collaborations with producers such as DJ Mustard and Helluva. Both rappers have rapid-fire deliveries that should complement each other well at tonight's concert. (Niesel)
