Apple yesterday held its formal opening of Apple Park, including a concert on the rainbow stage at the center of the campus. Lady Gaga performed at the event, with Apple Park employees taking to Twitter and Instagram to share photos and videos.

A drone video of Apple Park last week showed the mysterious rainbow stage at the center of the Apple Park spaceship ring. The stage was eventually confirmed to have been designed by Jony Ive, with the executive explaining his motivation in a post on Apple’s intranet. The event was described as a “celebration” of Apple Park’s official opening and a tribute to Steve Jobs:

The colors are reminiscent of the original Apple logo, with Apple expanding the rainbow design this week to various different parts of Apple Park, including stairs, cafe cups, and more.

Tim Cook took to Twitter to express his love for Steve Jobs. He thanked Lady Gaga for her performance in a separate tweet. “We came together today, in the home you imagined for us, and celebrated your spirit. We love you, Steve,” Cook wrote.

Lady Gaga fan blog LGN has posted a detailed recap of the event, including the artist calling on Apple to create a “Be Kind” emoji and dedicating her performance of “Million Reasons” to Steve Jobs. She also thanked Zane Lowe for his support on Apple Music and beyond:
