British house music production duo. Before calling themselves the "Rhythm Masters", Chetcuti & Mac worked under a series of aliases such as [a=Rhythm Robbers], [a=R.M. Project], and [a=Masters Of Rhythm]. Contracted as remixers, they left their mark on many club hits of the late 1990s-early 2000s, including hits such as [a=Todd Terry] "[m=77989]" (1996) and [a=Mutiny] "[m=86746]" (2000). Their album "[m=140811]" (2001) contained the singles "[m=140821]" (2001), "[m=140816]" (2001), and "[m=140818]" (2001). Further singles were planned, but the Rhythm Masters split not too long after, citing creative differences. Later on they came back together for different projects. The release of delirious electro/house single "[m=2024662]" (2005), showed once again their ability to deliver strong club cuts.
