New Jersey's Harry "Choo Choo" Romero has a locomotive moniker, but the house DJ and producer isn't known for train-wrecking records. Instead, he's managed to remain relevant in a fickle scene since the mid-1990s. Subliminal Records, the label he founded with Erick Morillo and Jose Nunez, is one of the lone titans among so many fallen soldiers in the dance music industry. Romero's keen sense of a propulsive groove has made him a favorite as a pop remixer too, and in recent years, he has even made a mark with a downright soulful house version of Korn's "Evolution." Catch Romero shifting contexts on Friday at La Covacha.
