[Watch] Karmin - "I Need A Doctor" Feat. Skylar Grey (Live for Billboard @Lollapalooza)

Soul Culture points to this interesting take on Eminem and Dr. Dre's hit track "I Need A Doctor" from the youtube sensation that is Karmin. Recorded for Billboard at Lollapalooza, they begin with a variation on the original using a stomp box and acoustic guitar before being joined by Skylar Grey herself midway through the track. The performance is great and it's nice to see that all the artists have a mutual respect for each other, so much so that they'll step in and sing with one another at any given opportunity.
