Indie rock band STRFKR, which hails from Oregon, USA, announced on its Twitter on Wednesday that the band would not be able to continue with its debut show here because the authorities had barred them from entry.
According to the band, the reason they were barred was because they held "positive views on marijuana".
The ban comes as no surprise as Singapore's drug laws are among the harshest in the world.
The organizer of the concert has also posted a notice of the show's cancellation and assured ticket holders that refunds are underway.
"Symmetry Entertainment and STRFKR are both saddened to announce the cancellation of the highly anticipated debut show by the band in Singapore. We were both excited about the performance and tried our best to make this happen but due to reasons beyond our control, STRFKR will be unable to enter Singapore for a performance.
Full refunds will be carried out for tickets purchased via our official Ticketbox page. The refund process may take up to 10 working days and ticket-holders will be sent an email with further information by Friday 29th September.
