NEW YORK - Rock 'n' roll had Buddy Holly, the psychedelic era had Jimi Hendrix and Janis Joplin and grunge had Kurt Cobain. Now electronic dance music has Avicii.

The Swedish DJ's death on Friday at age 28 marks a symbolic coming-of-age for a genre that remains resolutely youthful, with the first electronic superstar to die near his prime.

Avicii, the stage name of Tim Bergling, was not a first-out-the-door pioneer of electronic dance music - or EDM - a scene that has exploded since the turn of the century and last year was worth $7.4 billion, according to a study by the industry's International Music Summit in Ibiza.

But Avicii both showed the mainstream possibilities of EDM - and, by the end of his short life, had already become a sage elder who cautioned about the artistic and commercial overreach of the music.

Avicii came to define the new age of radio-friendly EDM in 2011 with Levels, which entered the top 10 across Europe with its sample of soul great Etta James in between synthesizer riffs that soar with stadium-packing power.

Non-clubbers also heard EDM's energy when Avicii teamed up with rockers Coldplay on Sky Full of Stars, with Chris Martin's voice giving way to fast-building, synthesized ecstasy.

But perhaps his most influential moment came in 2013 when he headlined the Ultra Music Festival in Miami. A year after he invited Madonna as a surprise stage guest, Avicii befuddled a crowd of ravers by bringing out a bluegrass band with a banjo for his soon-to-be-hit Wake Me Up. In an interview shortly afterward, Avicii warned that EDM was moving too quickly into a sound too hard and unmelodious, saying that audiences would soon tire of it.

"Since it got so big in America the past couple of years, dance music is taking over everywhere," Avicii told the London Evening Standard. "It's important that it keeps changing so it doesn't become a fad."
