Baltimore club's tempo rose from 125-128 BPM to 130+ and keeps accelerating

Baltimore club originally ran at 125-128 BPM, close to UK rave and fast house. By the mid-2000s the standard had shifted to 130 BPM, and tracks have kept getting faster since. The most extreme, fastest tracks — called ‘Battle’, ‘What’, or ‘Shakeoff’ tracks — belong to a scene of dedicated teen club dancers who use them for competitive dance, and that dance culture partly drives the acceleration since faster tempos demand more physical virtuosity. When producing or DJing club music, tempo choice signals which era or sub-scene a track belongs to.

Examples

A ~127 BPM track reads as mid-period Baltimore club; a very fast ‘What’ track targets the competitive Battle scene. A DJ must plan for this BPM spread when sequencing a set.

Assessment

State the original Baltimore club BPM range and the later standard, and name what the fastest sub-style tracks are called and the scene that drives them.
