Ever since Williams founded Sydney's The Metropolitan Orchestra (TMO) 13 years ago she has embraced the full gamut of musical styles. TMO has performed with English electronic duo Basement Jaxx, soft-rock legends Air Supply and brought to life the catalogue of Joy Division with Peter Hook.

TMO's latest show Synthony is perhaps their most innovative yet. It features a 60-piece orchestra performing iconic electronic dance music classics from artists like Avicii, Tiesto, Daft Punk, Eric Prydz and Bob Sinclair with guest appearances from Savage, Emily Williams, Mobin Master, Greg Gould, Cassie McIvor, Andy Van, Matty O, and Ilan Kidron from The Potbelleez.

"When this marriage, this EDM/orchestra came about, I was incredibly excited by it," Williams said. "We don't need to have all these walls and barriers between our different genres of music, there's no reason for it."

Synthony debuted four years ago and last month it returned to a sold-out Sidney Myer Music Bowl in Melbourne, with the likes of pop diva Dannii Minogue spotted in the audience.

Synthony is arranged by Ryan Youens (London Metropolitan Orchestra, Budapest Scoring Orchestra) and curated by Kiwi Dick Johnson (Fatboy Slim, Naked and Famous). Williams said Youens' arrangements bring a new dimension to classic EDM tracks like Destination Unknown and Don't Hold Back.

"There's a lot of shows in the cross-over world where you might have a pop group and a orchestra on stage, but it's more playing long notes in the background," she said.

"It's more of a visual thing than an aural thing. This orchestra is visual as they're getting into it and dancing in their seat, but the orchestra is used very well, so you can see the full scope and capabilities of what an orchestra can do."

Williams, herself, is also a major part of the show. There's no stuffy conducting during Synthony. Rather she dances like a pop star while in command of TMO.

"I certainly do not conduct Mozart the way I conduct Synthony," she said. "Synthony is a dance festival, it's a dance concert. A dance party.

"If I'm the person in front and I'm not getting amongst it, then it kind of looks odd. I have to approach it in a totally different way.

"In front of me I have all the information and my job is to unify a massive force of musicians in front of me and we've got to all come out in a cohesive thing.

"I'm there to inspire them, to guide them, and to really ignite something in them, and in turn, they give that back in spades."

Synthony debuts at the Wollongong's WIN Entertainment Centre on June 24 and Newcastle Entertainment Centre on July 22.
