Jet-setting Irish duo Bicep return to Will Saul's Aus label with two steady analog techno grooves ready for deployment in either their own wildly celebrated sets or those of any DJ looking for modern dance tracks that are still faithful to the classics. Using gritty, vintage-sounding rhythm sections as solid foundations, each track gradually builds up its own lush, melodic embellishments overtop -- "Circles" stays true to its name with a cyclical main melody, shadowy bass and fuzzy house pads, whereas "NRG106" sets spacey, dramatic chords and breathy vocals against the insistent, chittering machine percussion.
