'Club music' names a branching Baltimore-Philly-Jersey lineage, each city mutating its predecessor

In the US Mid-Atlantic/Northeast, ‘club music’ specifically means Baltimore club and its two derivatives, Philly and Jersey club — not generic dance music. Baltimore is the source; Philly and Jersey are local mutations triggered by exposure to Baltimore records. Each kept the basic scaffold (fast kick pattern, rapid vocal chops) but adapted tempo, timbre, and dance culture. The lineage is a practical genre-ID tool: a ~130 BPM aggressive track with the Think break reads Baltimore; a ~145-150 BPM track with detuned saws and sirens reads Philly; a smooth 140 BPM track with the bed-squeak reads Jersey. Producers should know which branch they are extending.

Examples

Jersey club (the smoothest branch) has been cited as an influence on commercial dance-pop; the Baltimore branch reached wider audiences via Blaqstarr’s work with M.I.A. and Diplo.

Assessment

Order the three club variants by tempo from slowest to fastest, and identify which derivative introduced hardstyle-style detuned saws.
