Rhymester (official website) is a popular group of three established men; Utamaru, Mummy-D & DJ Jin. And I'll be honest. I've never heard of this group or listened to their material (with the exception of Mummy-D who has appeared on a couple of things). Their upcoming album "Heat Island" to be released on the 8th of this month will feature a track which will have the Rip Slyme MC among others.

18. Weekend Shuffle - featuring MCU, RYO-Z, KREVA, CUEZERO, CHANNEL, KOHEI JAPAN, SU, LITTLE, ILMARI, GAKU-MC, SONOMI, PES, K.I.N, Dohzi-T

It seems Rhymester has had ties with Rip Slyme for quite a while. Though it is nice to see Rip Slyme in other works (though sadly still Fumiya-less)

I have noticed the link to the torrent I had posted is now gone. I have no idea what has happened but I downloaded the torrent right before it was removed. I'm just downloading it slowly right now and will upload it as soon as it finishes!
