German producer Roland Appel's "Dark Solder" was one of the most played house records of recent years, and it sounds like "Fleurs Du Mal" may emulate it. Appel's productions are straightforward yet full of feeling and the chord-heavy title track is a case in point, building to the sound of spooky vocal samples and filtered bass stabs. The end result is an eerie, utterly distinctive tech-house track. "Rosario" is a crisper drum track that also features building chord sequences, but it's "Black Leather" that steals the glory. Based on a relatively similar framework, its chiming bells are enchanting and, coupled with a wailing banshee, makes for the spookiest, tranciest (with a small 't') house this side of David Alvarado.
