[2] The group was founded by the native English and Swiss citizen Oliver Baroni (vocals, bass, guitar) and Italian-Swiss singer Emanuela Hutter.

The original formation was completed by drummer Aad Hollander and guitarist Pat Matteo, another former member of the Hillbilly Headhunters.

In 2006 after the release of All Grown Up, Englishman Duncan James replaced Patrick Gese on guitar and Swiss Luke Weyermann the new drummer.

In 2010, Hillbilly Moon Explosion appeared as the opening act for Jeff Beck in Paris Olympia.

On the album Buy, Beg or Steal, in the song "My Love for Evermore", Hutter sang a duet with Mark "Sparky" Phillips from the British psychobilly group Demented Are Go.
