Dutchman Robert Nickson reserves his RNX alias for his lower bpm productions; such as the 126bpm Original Mix of the Pure Trance 4 gleaned Colorado, which kicks off this package. Firstly it's a beautifully spacious, melodically intricate piece of lush pure trance music. The main synth hook is wonderful as expected from a producer of Nickson's calibre, but musicologists will also love the great middle bit (not a technical term!) where the track takes a diversion into deeper territory. This is something quite unusual in a trance record these days perhaps. For his Pure Trance 4 version, Solarstone reconstructed the track into something more befitting his DJ sets, raising the tempo to 136bpm, recreating the rhythm and bass tracks and reprogramming the focus of the arrangement on the main hook. Pure class.
