for backliners this is band is a joke. the one that doesn't know them gets to do the backline for them
in clubs the sound (especially the bass) is so loud you notice the air movement when you open a door. standing right in fornt of the PA set in the frontstage makes you sick.
they play with various setups, i know they used an all moog synth setup, but also bass, guitar, voice, some kind of mathematical old hewlett packard machines...
the wall of amps is a returning thing.
last time i saw them on a festival we had to set up 8 ampeg 8x10 cabs, 2 SVT classics, 2 SVT II, 2 SVTII pro, 2 marshall full stacks and they also had 2 hiwatt full stacks with them. everything DIMED.
more than two hours later the SVT's were still really hot (the amp itself, not only the tubes) they are great to have a laugh on a busy festival day
