Laboratory Instinct grace our shelves with the third in a quartet of 12 inch releases that act as the vinyl version for A Guy Called Gerald's recent and rather sleek ''Tronic Jazz'' album. Your attention on Side A will dominated by the spectral dalliance with vintage Detroit techno mechanics of ''Iland'', with expertly layered syncopation reverberating around to a backdrop of cavernous throbbing bass and dreamy synth lines. This contrasts nicely with the neo techno futurism of ''Just Soul'' with melancholic strings slipping between tense off-kilter drum programming and bubbling atmospherics. Proceedings shift up a gear on ''Round Eco,'' which pulsates with menacing KiNK-ish energy, with an odd vocal murmur forming the driving groove around which Simpson wraps glacial keys and deviant bass twinges. Closing track ''The Dip'' oscillates wildly with B movie sci fi synth lines and scratching metallic tones.
