John Heckle last released an album on Tabernacle three years ago, but he s been far from quiet since then with his Head Front Panel project diverting his attention towards blistering hard techno. Tone To Voice then represents a return to more melodic pastures with a more diverse selection of tempos and moods to choose from, but still Heckle s innate gift for expressive, dynamic machine music shines through. -Sonic Spectrometer- is a joyous slice of techno-jazz, while -Potential Life- whips up stunning cascading synth lines and pattering hats. At times, there s no need for a kick, and with ample ambient excursions woven into the mix this stands as one of Heckle s most accomplished releases yet.
