When people say there's a lot of cameo artists in this album they MEAN IT! Like.. a SHITLOAD! and of all kinds! I don't even know how I ended up buying this but I'm damn glad I did. I was looking up Kid Koala stuff and the name of this all-star duo just caught my attention. After listening to the CD I must say this is definately how hiphop should be always produced. There's all sorts of styles in this CD and they all just sound awesome. Especially the Rock N' Roll song, I'm amazed how they incorporated the hiphop beats to that classical piece (I think that's Vivaldi's "4 Seasons"?) and when I heard Chester and Mike from Linkin Park I was just like "WHAT THE HELL! AWESOME!" and then in The Hours you can definately hear the influence of Deftone's Chino Moreno along with his vocals. Even Jack Johnson is here! Seriously, this CD is filled with too many cameos.. Just go get the album and listen yourself..
