Hillbilly Moon Explosion originated in 1998 as part of the Zurich rockabilly scene.[2] The group was founded by the native English and Swiss citizen Oliver Baroni (vocals, bass, guitar) and Italian-Swiss singer Emanuela Hutter. Oliver Baroni was planning to leave his former band, the Hillbilly Headhunters. Emanuela Hutter worked with the singer/songwriter music project MD Moon at that time. The original formation was completed by drummer Aad Hollander and guitarist Pat Matteo, another former member of the Hillbilly Headhunters. The first demo tape was made in the same year. Emanuela Hutter was at the time bound by solo performances and did not enter the band until the following year. In 2006 after the release of All Grown Up, Englishman Duncan James replaced Patrick Gese on guitar and Swiss Luke Weyermann the new drummer. Frenchman Sylvain Petite later took over drums. In addition to touring and performing in Switzerland, the band have performed in other European countries including Germany, France, Spain, Italy, Finland, Slovenia, Croatia, Hungary, Poland, Austria and the UK. In 2010, Hillbilly Moon Explosion appeared as the opening act for Jeff Beck in Paris Olympia. In both 2018 and 2019, they also toured the west coast of the US. The members of the group live in and around Zurich.
