Courtney Love's Sound Engineer Didn't Get Paid So He Isolated Her Vocals and Guitar. Good God...
This is what happens when you don't pay your sound engineer... and when you sound like complete shit. This is a video of Hole performing Celebrity Skin live at Don Hill's in NYC, Sept. 11, 2010. The sound engineer for the show that night (and other nights that week) allegedly didn't receive payment for their work at the venue, so one sound engineer decided to get revenge by isolating the singer/guitarist's vocals and guitar from the rest of the performance, resulting in nothing more than nails on a chalkboard.
The video is said to be someone else's live footage.. all that changed was the original audio was muted and the live recordings of the same performance were synced with the video.
