Many fans in Madison may not know this, but the rock band Disturbed was just in town for several days to tech their current tour. Teching , or technical rehearsals, are when the talent and the production finally come together to build a performance. It's been a treat for the Madison Stagehands to have the Disturbed musicians and crew at the Alliant Energy Center this week. Indeed, having them here for more than one day did mean more than one day's pay for stagehands, which is awesome, but it's much more than that.
