A live symphony concert event tonight in Los Angeles is one of the events marking 25th anniversary of Nintendo’s iconic The Legend of Zelda. Attendees are encouraged to attend in appropriate costumes, adding to the celebratory atmosphere, but are asked to leave the swords at home.

A 70-piece orchestra along with a choir will perform new arrangements of songs and musical themes from the franchise. Additionally, Nintendo will be there to offer hands-on demos of the two latest games in the series: The Legend of Zelda: Ocarina of Time 3D (pictured) for the Nintendo 3DS hand-held system, and the  Legend of Zelda: Skyward Sword, which launches for the Wii system on Nov. 20.

The event will be held in London on Oct. 25 following tonight’s show at the Pantages Theatre. It is produced by Jason Paul Productions, Inc., which also produces the Play! A Video Game Symphony concert series.

The Legend of Zelda franchise has sold more than 62 million games worldwide since its 1986 launch.
