The Threshold HouseBoys Choir has been played on NTS over 30 times, featured on 30 episodes and was first played on 16 June 2017.

The Threshold HouseBoys Choir was a musical guise for Peter Christopherson, announced in 2005 as a follow up endeavor to his former group Coil. Despite the misleading name, it was a solo project which relied heavily on computer generated vocals, of which he was formally credited as the 'director'.

The name was derived from a play on words, combining the phrases 'house of boys', 'boys' choir', and 'Threshold House', the latter being the name of Coil's former headquarters, and official website.

THBC was stationed in Krung Thep, Thailand.

Peter Christopherson passed away peacefully in his sleep on November 25, 2010. Instead of sending flowers in memory of Peter Christopherson, people were asked to donate money to help children affected by AIDS in Thailand, the country he loved and died in.
