Ska band vs rap heavyweight.
He's arguably the biggest rapper in the industry right now and though Kendrick Lamar is unsurprisingly aiming for the #1 spot on the ARIA Albums Chart with his surprise compilation record, Untitled Unmastered, the US hip hop artist will have to fight off Aussie ska/jazz veterans The Cat Empire to claim the coveted top spot.
The Melbourne-founded outfit's seventh studio album, Rising With The Sun, has been a hit with critics and fans alike (as well as scoring our pick for Album Of The Week) and subsequently is not only primed for a top three placing, but is also chance to spoil Lamar's party.
The Cat Empire could score their second #1 if they do win out the battle, following on from their 2005 offering, Two Shoes.
Meanwhile, if Lamar was to take out top spot, it would mark his second-straight Aussie #1 after his acclaimed 2015 album, To Pimp A Butterfly, peaked at top spot, as well as picking up a bunch of Grammy Awards last month including Best Rap Album, Best Rap Performance, Best Rap Song and Best Rap/Sung Collaboration.
