hi rotterdam!
hab da zufällig was gefunden im web daß dich vielleicht interessiert
:
Rotterdam: Dark 4-beat, emerged from Hard Trance. Pounding distorted bass kick. About 180-220bpm. There are only a few places in the world that actually differentiate between Rotterdam and Gabba, mainly Toronto, some places in California, and a few places in Europe. Nowadays, the term Rotterdam refers more to something sort of across between happy hardcore and gabber.
greetz,
