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.
Hopefully Spanish producer De La Calle's catalogue is never the subject of a Robin Thicke-style action because it contains so many familiar-sounding samples. This release on Swiss label Mental Groove is a case in point: "Mental Jazz" starts off with hissing percussion and dubbed out chords, while a muffled, indistinct man witters on in the background. However, it's the melancholic trumpet sample that takes over the track midway through that will make his listeners ponder where they have heard it before. Similarly, "Vasudevas Wonderland" is based on a croaky, dubby track, but it's the eerie, Drexciyan synths that will arouse curiosity about whom De La Calle's compositions are inspired.
