Alex Whitcombe & Simon Duffy return to 2011with a bang! Their latest single 'Spectrum' is Progressive House at its best. Simple but tough, melodic but groovy whilst beautifully produced and arranged to give you that 'close your eyes' moment every dance floor craves for! Tough beats and percussion develop with deep glitch and bleeps as the 'Moroder' style bassline builds effortlessly to the perfect breakdown which then propels "Spectrum" into dance floor heaven. Definitely a track that needs to be heard out loud on a quality sound system. The collaboration between Alex Whitcombe & Simon Duffy has been a prolific one these past 12 months with tracks such as Rotation, Abacus, Cycles, Rouge and Eclipse headlining various dance floors across the globe with critical acclaim. 'Spectrum' with its collaboration of driving bass, tweaks and peaks has the perfect mix of dance floor elegance with its huge melodic synth hook rubbing shoulders with magnified sweeps, tough beats and a groove big enough to dispel even the most boring of dance floors. 'Spectrum' definitely hits the spot in more ways than one and is sure to be a permanent fixture in many a record box these next few months.
