His use and support of the Moog synthisizer was critical to the company's development of new instruments, and he often played early prototypes like the Constellation, a three-keyboard polyphonic synthisizer.
In the late 1960s, future Motorhead frontman Lemmy Kilmister was a roadier for the Nice and gave Emerson the dagger that he would often hurl at his Hammond organ during shows.
Emerson's Yamaha GX-1 synthesizer was so large that it required eight roadies to move it.
His interest in the Hammond organ came after hearing jazz musician Brother Jack McDuff.
ELP rose to fame shortly after their appearance at the 1970 Isle of Wight Festival, where they fired cannons from the stage as part of their show.
At the height of ELP's fame, Emerson would frequently take part in a stunt which found him at a piano that was raised 15 to 20 feet in the air and turned end over end while he played it. Jazz great Dave Brubeck was reportedly a fan of this particular stunt.
With ex-Rainbow drummer Cozy Powell, Emerson and Greg Lake formed the short-lived Emerson, Lake and Powell in 1986.
In 1990, he briefly toured with John Entwhistle, Joe Walsh and Jeff "Skunk" Baxter in a supergroup called The Best.
Emerson was joined by Chris Squire and Alan White of yes and Bad Company's Simon Kirke as the opening act for the Led Zeppelin reunion at the 02 Arena in London in 2007.
