It looks like the redo of the Mirage volcano is finished:
The volcano even had a blog!
Looks like WET Design was involved again, and it uses a Meyer sound system (press release from the Mirage):
. . . Known the world over for its iconic Strip-front feature, The Mirage has joined forces with legendary Grateful Dead drummer Mickey Hart, Indian tabla sensation Zakir Hussain and Fountains of Bellagio design firm WET, to create an all-new audio/visual spectacle. The top-to-bottom overhaul is the final step in the property's ongoing transformation and is scheduled for completion late 2008.
The Mirage set a new standard for innovative Strip-front attractions when The Volcano first erupted in 1989. Raising the bar once again, The Mirage has enlisted the Grammy Award-winning talents of Rock and Roll Hall of Fame musician Mickey Hart and Indian musical virtuoso Zakir Hussain to create and perform a one-of-a-kind soundtrack arranged exclusively for the iconic blast.
"To put percussive sound to the image of fire and have it dance around a lagoon is something I've never done; I've never birthed a volcano," said Hart. "Zakir and I immersed ourselves in the legends and myths and studied what really makes a volcano work. The result, a true union of the senses, will rattle your bones, just like a real volcano."
Tasked with bringing the latest innovations to the project, WET will forge a primal volcanic environment of sound, light, music and heat. WET's choreographed FireShootersTM - which send massive fireballs more than 12 feet into the air - were designed specifically for The Mirage using the latest developments in flame-expression technology. The FireShootersTM will punctuate the performances with eruptions of fiery "lava" that will flow down the mountain's fissures in a series of lively flames. As the eruption ignites the surrounding lagoon, the FireShootersTM will bring Las Vegas' signature blast within feet of spectators.
Further enhancing the overall experience, The Volcano will feature a new Meyer Sound state-of-the-art sound system. An award-winning industry innovator, Meyer Sound is widely recognized for providing the gold standard in audio systems, as heard in theaters throughout the world, including The Mirage's own LOVE Theater. With more than 60 Meyer Sound cabinets strategically placed throughout the lagoon, Hart and Hussain's invigorating composition will immerse guests in the volcanic rhythm.. . .
