There were several musical disciplines being explored during this era that fell into WH nomenclature because that was the hype and it was easy to pen in. It was an amazing experience but I think it is well and truly dead.
Besides those you mentioned, I loved Black Ceiling, Mascara, Salem, White Ring, oOoOO, Ritualz, Valhall, Unison, Bathaus, Eyedoublecross, Mahr, Wikan, and Crimes. Most of these projects just had 1 or 2 actual albums and then they faded out.
