Tools.
If you get kicked out of a Tool show for shooting video on your cellphone, well, that's on you. The band is giving fans / psychedelic warriors ample heads up that this behavior is not permissible and will lead to an ejection with no chance of re-entry.
Maynard James Keenan has been outspoken in the past about his disdain for fans not living in the moment and soaking in the show. In his view, the use of a phone, and shooting keepsake videos in particular, only serves to "demystify" the experience.
