LWE’s Kuri Kondrak caught up with South Africa’s RezKar two weeks ago, noting the promise of big things to come. RezKar’s newest, one track backed by four remixes on the Running Back label, is significantly more assured, without quite seeming to realize the potential present in earlier efforts. There are a number of very good things in the original mix of “Above the Clouds”: pretty melodies that dance through artful synth arrangements, defying both hands in the air schmaltz and limpid disco house recombinations. This is a good trick to know, and the track generally betrays a good ear and considerate attention to musical quality. But carefully negotiating a divide that has at its one end Gui Boratto and its other Prins Thomas is an insufficient accomplishment for someone whose earlier output promised galloping individuality.
