I'm a fan of Tony Mahoney first and foremost. And secondly I have worked with him on a couple of tracks (see previous post as Marble was produced by him!).
He's done a few beat tapes that are floating around the web as well as 2 EP's with Ragz Sweet Jones and speaking of which I did cuts on one of said EP's for a track called "Sex, Drugs and Hip Hop" which is posted under this.
Make sure you follow him if your on Soundcloud and YouTube as he keeps everything updated regularly.
