LAS VEGAS (AP) — Phish opened its four-night stay at the Sphere Thursday with a four-hour show that used the advanced technology in the $2.3 billion arena to deliver a show that even the band’s most ardent fans have never experienced before.

“We came in really wanting to do a show that was a great Phish show,” said Abigail Rosen Holmes, who is running the visual show. She said the band and its creative team wanted to mix the Sphere’s technical capabilities and consider “what can we do for Phish that we maybe couldn’t do for any other artist?”

Here’s how Phish is creating a set of shows that even fans who’ve seen the band perform hundreds of times won’t have experienced before.

TAKING THE MUSIC ON SCREEN

While Phish shows usually get their visual punch from lighting guru Chris Kuroda’s massive lighting rig, these shows are completely different as the band uses custom visuals on the 160,000-square foot 16K-by-16K LED screen.
