It's clear from these tracks that Eduardo de la Calle has developed a unique touch during his twenty-year stint as a producer. "Never Summertime Again (re-modeled mix)" is a sensous but earthy house arrangement. Its rasping percussion and heavy beats provide the basis for shimmering keys, but also later on a darker tone as the Spanish producer introduces malevolent acid lines. De la Calle also has an experimental streak, as "E2E4 (Rave Signal re-work)" demonstrates. Featuring plink plonk keys which appear to be providing an intro for another house groove, de la Calle then surprises with abstract sheets of percussion and disturbing tonal blips and bleeps.
