Sarah Whatmore – When I Lost You is a classic early 2000s vocal trance and progressive house release that captures the melodic side of British club culture during the era. Released as a promo 12 inch vinyl by BMG UK & Ireland, the record features multiple club-oriented remixes connected to progressive house, vocal trance and funky house crossover sounds.

The A-side includes the K-Klass Ultimate Vocal Mix, one of the strongest versions on the release. Groove-focused rhythms, uplifting house arrangements and melodic vocal elements reflect the signature style of the British house duo K-Klass. This type of progressive house vinyl sound became especially popular in early 2000s UK club culture, where vocal house and trance increasingly blended together.

On the B-side, the K-Klass Pharmacy Dub Mix moves toward a deeper and more groove-oriented atmosphere. Reduced vocal sections and longer instrumental passages reflect a period when dub mixes played an essential role in vinyl DJ culture and underground house music environments. The release remains both melodic and club-focused while maintaining a warm progressive house atmosphere throughout.

The Flatline's Whatever Next? Monkey Tennis Vocal Mix introduces a more direct dancefloor energy with stronger vocal trance and progressive club influences. The combination of uplifting synth themes and rolling grooves fits perfectly within the crossover electronic sound popular in the UK dance scene during the early 2000s.

This vinyl release represents an important period when progressive house, vocal trance and funky house styles became increasingly connected across European club culture. The record naturally blends melodic vocals, groove-heavy house rhythms and trance-inspired atmospheres.

K-Klass became one of the most respected names within British house and remix culture from the 1990s onward. Their productions and remixes played an important role across vocal house, dance and progressive club music scenes.

For collectors, this promo 12 inch vinyl is a strong addition to trance vinyl, vocal house record and early 2000s progressive house collections. Its promo-only character adds extra collector appeal for fans of UK club music culture.
