T.Williams sits near the forefront of a group of producers twisting elements of grime and funky into a rough-edged strain of UK house. His Rinse: 21 mix takes the form of an hour-long, club-centered set. It begins slow and soulful, before slowly escalating through several different phases. A feeling of acceleration characterizes the mix's first third, before Williams sinks into shimmering, loop-driven peak-time house for its middle section. It's around this point that the presence of grime -- the genre that T.Williams first made his name in -- begins to make itself felt. Grime and funky are reprised during the mix's final third -- a potent reminder of the pressure that still lurks behind the often smoother surfaces of Williams' peak-time selection. A series of ruff-neck grime/house hybrids follow, bringing the mix to a close in an exhilarating and playful blur of aggression and synthetic texture -- and in doing so, hark neatly backward to Williams' own roots, and those of Rinse FM itself. Artists include: Tendai, Juno Sutton, Soul Clap, Breach, Nitetime, Himal, Disclosure, Groove Control, Tuff Jam, George Fitzgerald, Aphrodisiax, Huxley, Eats Everything, Dusky, Maya Jane Coles, Breach & Midland, Julio Bashmore, MTD & Dutty Dan, Jessie Ware, Roska, J.
