Robert Pattinson's girlfriend FKA twigs is one busy performer. After wrapping up her Soundtrack 7 residency in Manchester, England, the singer recently gave a rocking performance at the Fuji Rock Festival in Japan.

“Hi Japan,” twigs wrote on her Twitter on Sunday, along with a link from a Japanese website. According to Google translation, the link talks about her performance at the festival. The link provided by the starlet also reveals some information about her new song, “MV,” which she reportedly sang there.

Billed as Japan's largest rock event, the Fuji Rock Festival boasted this year an impressive lineup including the Foo Fighters, Muse, Noel Gallagher's High Flying Birds and Motorhead, Billboard writes. The Foo Fighters headlined the opening night, followed by Muse, who belted out "Psycho," "Supermassive Black Hole," "Dead Inside," and "Uprising" on the Saturday night.

Sunday night was dedicated to Gallagher and twigs. After his performance, twigs made her entrance with “her three-drummer, beat-and-bass-synth heavy electronic set that entailed waves of sound washing over the audience,” writes music critic Rob Schwartz from Billboard. He also calls her voice “angelic” and said that singer gave a “mesmerizing” performance on contemporary dance.

Twigs won positive reviews for her performance. The critic also writes that she “performed constantly throughout the set, made the presentation thoroughly compelling.” Her fans are now curious about her new song “MV,” which she reportedly premiered during the rock fest, according to Japanese website Hostess.

Meanwhile, twigs is also excited that her song “Pendulum” has earned an Artist to Watch nomination at the 2015 MTV Video Music Awards. The British songstress shared the information on Twitter.

The Fuji Rock Festival is currently in its nineteenth year and drew more than 100,000 attendees. The festival was held from July 24-26 at Naeba Ski Resort in Niigata. Ticket sales garnered revenue of 3.17 billion yen ($25.6 million).
