A Swiss rockabilly combo, the Hillbilly Moon Explosion exists in a middle ground between the traditionalism of many rockabilly revival bands and the rougher, spookier sound of psychobilly. Founded by vocalist and rhythm guitarist Emanuela Hutter and bassist/vocalist Oliver Baroni, their music has more than its share of retro twang, with Hutter's polished, enigmatic singing blending with the sometimes raucous, sometimes moody guitar lines, and they add dashes of punk, lounge pop, country, and even ska to season their evocative mix.

The band staked out their trademark sound on 2002's Introducing the Hillbilly Moon Explosion, they fully hit their creative stride on 2011's Buy Beg or Steal, and they collaborated with psychobilly veteran Mark "Sparky" Phillips for 2019's The Sparky Sessions.
