British jazz musician Jacob Collier will perform a second concert here at the Singapore International Festival of Arts, taking the stage at the Victoria Theatre on April 28.

The Grammy Award winner was originally scheduled to do a single ticketed event on April 27, but it sold out on Feb 21, two weeks after the performance was announced. His free talk on April 28 at The Arts House is also fully subscribed.

Collier, 24, is one of the headline acts at this edition of the annual arts festival, which runs from April 26 to May 12. The London-based multi-instrumentalist won viral fame on YouTube with home-made videos of himself singing in harmony in split-screen. His trademark is performing covers of cartoon theme songs and popular melodies.

One of his online fans was record producer Quincy Jones, who signed the musician with his management company.

Collier's debut album, In My Room, was released in 2016. His rearrangement of the theme to the 1960s cartoon The Flintstones won a Grammy Award last year for Best Arrangement, Instruments and Vocals. He also won the Grammy for Best Arrangement, Instrumental or A Cappella for his cover of Stevie Wonder's You And I.

Collier's extra concert here is ticketed at $40 and the front row of the Victoria Theatre will be reserved for students, who can buy tickets at $10 each. The $10 front-row seats have been reserved for students at almost all performances in the festival, as part of festival director Gaurav Kripalani's bid to bring in more young viewers.
