Check out this video from Bay Area hip-hop collective Team Back Pack for their song "Do That."

Team Backpack is a collaborative effort to help independent artists reach their fans. It's also been described as a "hip-hop/lifestyle movement" emanating out of the Bay Area. Now in its third year, Team Backpack brings together multiple MCs to "spit their hottest 16 bars" on original beats. They film the sessions and put them online, where fans can vote for their favorite verses.

One of the most recent videos to come out of the TBP is "Do That" featuring Armani Cooper, Jedi and (self-described "lyrical terror") Shark Sinatra.

Enjoy.
