Andrew Bright apologizes.First, his radio buzzes. Then, his phone rings. Its someone from Madison Square Garden.I do a lot of things like this, Bright said, but not on this scale.Bright is sitting in a small trailer on the street outside Washington Park. His official title is director of media server technology. For the BLINK festival, he describes himself as a programmer.In practice, hes more like a conductor.And hes busy.At Music Hall alone, there are 12 different projectors each one responsible for different pieces of the same light projection show. Its Brights job to make sure the projectors line up correctly with the building.His team does this from more than a football field away.Its able to triangulate where the projector is, he said. From there, were able to line up the other ones with the building.On the second-floor balcony of Music Hall, workers use a tape measure to move light fixtures an equal distance apart. Its an example of the mixture of high-tech and blue-collar work thats essential to a festival like BLINK.This is one show, Bright said, but its actually about 24 shows.Then, he laughs. And gets back to work. Justin Brookhart walks by Music Hall every day. Hes the executive director of BLINK. This year, he said hes most excited for the display here a 30-minute lighting and projection show featuring four different artists.BLINK is truly a massive production, Brookhart said. There really isnt very much like this in the United States.At Music Hall alone, there are more than 3,000 lights. It means the technology is just as important as the art. Every single site has its own logistics challenge, its own technology challenge, Brookhart said. Every single one of those sites probably had dozens of hands to bring it to life.Back in the trailer, Bright shakes his head.It even amazes me how big this job is, he said. Its going to be a fun week.MUSIC HALL EXPERIENCE:Cincinnatis historic venue will feature four lighting and projection shows. There will also be an organist performing during a program inside. Admission to the inside show is free. For more information, visit BLINKs website.You can also watch the opening parade anywhere you stream WCPO 9.
