Before the duo was formed, Josephine was a solo artist, first going by her own name and then later under the alias of “LAYLA”. Anthony was originally part of the bands Tonight is Goodbye, Futures, and We The Wild. The two first met in High Wycombe on 21 March 2010 when Anthony was in the audience at one of Josephine’s solo gigs. A year later Josephine attended one of his shows, talked with him, and they began writing songs and making music together.
The duo released their first two songs under the name “Wonder Wonder”, but changed it to “Oh Wonder” when they learned of another band with a similar name.
Since their debut album release, Oh Wonder has toured internationally in the United Kingdom, France, Belgium, Germany, Sweden, Norway, Denmark, Netherlands, Russia, Australia, Canada and the United States. Their performance in Manila was their first show in Asia. They also toured as the opening act on the final installment of the Badlands Tour with Halsey from 21 July to 12 August 2016. Their 2016 debut festival appearances included Bonnaroo, Firefly, and Lollapalooza music festivals in the United States, in addition to Live Out in Monterrey, WayHome Festival in Oro-Medonte, Canada, and Electric Picnic in Stradbally, Ireland.
