I saw the Orb last night. They are currently Alex Paterson and Thomas Fehlmann, who dj a maelstrom of amazing sounds. An electronic concert such as this is a different universe than a guitar/band based show.
I have felt a room vibrate before (Mogwai, Sonic Youth, etc), but this was a new world of sound.  The bass was carefully calibrated to make the room become an instrument in tandem with the roars and beats emanating from
the massive speaker system tuned to the room at Mill City Nights.  Sample based shows can work, and this was an inspiration, even to a guitar based musician such as myself.  I’ve listened to plenty of techno on the stereo, but that can’t compare to the immersive experience I was surrounded with last night.  The opener, KPT, was also excellent.
