Riot Games has debuted hologram technology for this year’s League of Legends World Championship final opening ceremony. Using a product called Holonet, a fabric mesh scrim with metallic filament woven into the fibers, and precise lighting in the arena,they were able to bring characters from the game to life with hologram effects.

Valerie Broussard of Philadelphia kicked off the holographic concert by performing “Awaken,” a song released earlier in the year to signal the beginning of the League of Legends calendar year. The debut single from augmented reality hip-hop group True Damage, “Giants,” consisting of vocals from Rebecca “Becky G” Marie Gomez, Jeon “Soyeon” So-yeon, Umar “Thutmose” Ibrahim, Jared “Duckwrth” Lee and Keke Palmer was also performed. In addition to these songs, the tournament’s anthem, “Phoenix,” was performed by Chrissy Costanza and Cailin Russo.
