Anna Kendrick‘s “When I’m Gone” and Kendrick Lamar‘s “Poetic Justice” just got a whole new makeover by mashup artist Isosine. Going head to head, it’s Kendrick versus Kendrick, with guest appearances by Drake and Florence and the Machine to join the assit in the ring. Based out of Canada, Isosine is known for his epic mashups and here’s the evidence to prove it. Rather than the traditional chop and screw template, “Poetic” flows ever so effortlessly. Unfortunately, it might be a while (or never) before we see these artists on a track together. So, until then we can pretend that Anna Kendrick and Kendrick Lamar dueled it out in the studio.
