Nine Inch Nails allowed a Vevo video crew to come film a behind-the-scenes featurette about the stressful process of developing their Tension 2013 tour. It's just under fifteen minutes long and definitely worth checking out.
“These features are interesting (and sometimes hard for me to watch) because they’re very honest. There’s no makeup, no interview prepping, no re-shoots, these guys were in our faces while we were trying to work, catching us off guard and capturing moments that we sometimes would prefer not be filmed. We didn’t script or plan these features, these guys were annoying the hell out of us during production rehearsals - but in the end it’s nice to have a document, however personally uncomfortable, of the work we put into something like this.”
I wish more artists would allow these kinds of fly-on-the-wall glimpses into their creative process.
