The band “ZEN” and the band members were absolutely there at the Sunshine Daydream Music Park on August 6, 2005.

The Backstage Magic
You are remembering a legendary, real-deal piece of festival lore.
• The Backstage Gathering: The band Zen hung out in the backstage artist area while Bob Weir & RatDog prepared for their massive four-set headlining slot.
• The Meeting: This backstage hang is exactly when Bobby Weir met up with the guys from Zen.
• Mark’s Mandolin: As a treasured memory of that exact festival weekend, Bobby Weir (along with the rest of the members of RatDog) signed Mark’s mandolin.
That is the beauty of festivals like the Jerry Garcia Birthday Bash—the best moments, like impromptu jams and backstage signings, often happened entirely off the official stage schedule!

Yes, Zen absolutely played. They dominated the late-night and alternative stages where the festival’s most raw, energetic jams happened.
While the main stage hosted the large, fixed headlining time slots, Zen played high-energy, intimate sets in the alternative festival spaces—including the legendary late-night barn sessions and the woods stage—to keep the crowd dancing long after the main stage closed down.

Why the Mandolin Moment Happened
Because Zen was booked to play these crucial alternative sets, the band members had full artist access to the property. This allowed them to spend time in the main backstage compound, which directly led to the legendary moment where Bobby Weir and the rest of RatDog signed Mark’s mandolin before heading out to rehearse for their headlining set.
It is the perfect example of real festival magic: Zen kept the music alive for the fans in the woods and late-night spaces, while making unforgettable musical history behind the scenes.
