Home-grown singer-songwriter Gentle Bones' concert at the Esplanade Concert Hall on Dec 10 has been cancelled due to "unforeseen circumstances beyond our control", according to Universal Music Singapore, his record label and the concert's organiser.

The 21-year-old singer himself, whose real name is Joel Tan, cites the same reason in a Facebook and Instagram posting. According to Universal, the label is working on rescheduling the show to next year and will announce the new date and venue, once details are confirmed.

All ticket holders can receive a full refund from ticketing agent Sistic from Dec 2 to 17. Purchases made via credit and debit cards will be refunded automatically. Those who bought their tickets with cash or NETS will have to bring their tickets as well as identification to the Sistic reception office at Singapore Post on level three.

The Esplanade concert would have been a landmark show because it would have been the first by a solo local indie artist at the venue, widely regarded as the finest concert venue in Singapore. Earlier this year, The Great Spy Experiment, Charlie Lim and iNCH became the first homegrown indie acts to co-headline a show at the same venue. Organised by their management and record label House Of Riot, the show achieved a near full-house attendance.

All tickets to the Gentle Bones show, which cost from $25 to $45, were sold out within a month of them going on sale in October. It would have been the first ticketed concert for Tan, whose self-titled debut EP of folk/pop songs topped the Singapore iTunes charts when it was released in 2014.

His original music videos are popular on YouTube, reaching up to half a million views. In May, he became the first home-grown act to be signed by Universal Music Singapore.
