With a sweet, high tenor voice, flawless English, and no trace of an accent, Danish pop sensation Christopher appeared seemingly out of nowhere in August 2011, already signed to EMI, which released a YouTube video where he performed an acoustic cover of Robyn's Call Your Girlfriend. The video instantly garnered thousands of hits, paving the way for his debut single Against the Odds in 2011 which reached number 23 on the Danish Singles Chart. Shortly afterwards, he won the Danish Music Awards 2012 and was awarded New Thinker of the Year, given by Spotify as an innovation prize. Christopher released four albums, the debut Colours (2012), followed by Told You So (2014), Closer (2016) and Under the Surface (2019).
