There's no way to explain this any better the creator, Franzoli Electronics, explains it in the description:

The main loud music really comes from the tesla coil sparks. They are literally playing the music due to the programmed phase, pulse width and firing frequency! So, there are no speakers, no audio / video special effects. It looks even better in person and sounds almost the same, just without the beat / percussion backing track.

At Weezer's show at The Forum in Los Angeles Wednesday, Weird Al got onstage mid-song to join the band in a cover of Toto's 1982 hit "Africa." You may remember that a 14-year-old recently convinced Weezer to cover "Africa."

Billboard:

"We're gonna take you on a distant voyage," promised singer Rivers Cuomo, who was sporting a classic sleeveless Nirvana T-shirt and rocking a flying V guitar. "To the continent of your choosing... where do you kids want to go tonight?" The question was rhetorical, of course, as "Africa" has become the highlight of the band's sets on their current co-headlining tour with The Pixies. Just moments after the crowd shouted "AFRICA!!!," the band kicked into the song's familiar heat mirage intro and Cuomo awkwardly played some air drums and then, just after the third verse, it happened.

"Weird Al" wandered out on stage in his signature Hawaiian shirt, his accordion at the ready to rip off a wicked solo. Al joined in on the chorus and finished it off with an accordion/guitar riff-off with Cuomo. And then, officially, summer was over.

Weezer revealed their cover of Toto's 1982 hit "Africa" on Tuesday.

It was a matter of "giving the fans what they want," as the Weezer fan Twitter account @weezerafrica began suggesting the band "bless the rains down in africa" late last year.

@RiversCuomo it's about time you bless the rains down in africa

In early December, Noisey reported that a 14-year-old Cleveland girl named Mary, "who has been learning Weezer songs in her School of Rock cover band," was behind the account.

Mary has been busy tweeting at the band members with her humble request and has been encouraging others to do the same. “it’s about time you blessed the rains down in africa,” she tweeted at Cuomo on Wednesday. Agreed, it is time. She even got a reply from drummer Patrick Wilson. “I laughed,” he said. But Mary, with a determined, unbreakable focus on her goal, replied: “thank you for replying patrick. it has made me feel almost as blessed as the rains down in africa.”

The band is currently on a North American tour. No word if they'll be playing the song live. Read the rest
