The global viral classical music comedy duo TwoSet Violin has announced a return to the Sydney Opera House Concert Hall in June – just over a year after announcing the “end of a chapter” on social media.

Australian violinists Brett Yang and Eddy Chen, whose online following approaches seven million, shocked fans in October 2024 when they declared via Instagram, Facebook and YouTube that it would be the “last piece of content” posted as TwoSet Violin after 11 years. “We’ve all grown up together and it’s kinda surreal that we’re ending our chapter here,” they wrote at the time.

The pair later resurfaced with a parody-pop release, I’m Bach, under the moniker B²TSM.

Now billed as part of their Sacrilegious Games World Tour, TwoSet Violin will perform on 9 and 10 June with The Metropolitan Orchestra, conducted by Sarah-Grace Williams. The concerts follow their sold-out Opera House debut in 2024.

“We’ve been practising 40 hours a day for this moment,” the duo said in a statement. “Returning to Australia to take over the Sydney Opera House feels surreal.”

Since launching their YouTube channel in 2013, Yang and Chen have amassed more than 1.5 billion views, collaborating with artists including Lang Lang and Hilary Hahn, and building a reputation for virtuosic playing, viral challenges and irreverent takes on the classical canon.

The Sydney program ranges from Mozart’s Marriage of Figaro Overture and Vivaldi’s Four Seasons to showpieces by Paganini, Sarasate and Tchaikovsky, alongside a new work, Anti-Brainrot Concerto by Nicholas Ma.

TwoSet Violin perform at the Riverside Theatre, Perth Convention and Exhibition Centre, Perth on 7 June; in the Concert Hall, Sydney Opera House, 9 and 10 June; Brisbane Convention & Exhibition Centre on 21 June and Festival Theatre, Adelaide, 24 June.
