Born in Hamburg in 1994, Jaehn studied classical violin in his youth before turning his attention to DJing in his teens. Around 2011, he briefly attended London's Point Blank Music College before returning to Hamburg. After reestablishing himself in Hamburg, Jaehn released several well-received singles, including 2014's "Dance with Me" featuring Thallie Ann Seenyen and 2014's "Shine" with Freddy Verano and Linying. However, it was his 2015 remix of OMI's "Cheerleader" that grabbed the public's attention. A catchy, reggae-infused dance hit, "Cheerleader" topped dozens of charts across the world. That same year, Jaehn earned yet another worldwide hit with his remix of vocalist Jasmine Thompson's song "Ain't Nobody (Loves Me Better)," a cover of Rufus Chaka Khan's "Ain't Nobody." Jaehn formed the duo Eff with singer Mark Forster, and their debut single, "Stimme," topped the German singles chart for three weeks.
In 2016, Jaehn issued a handful of notable singles, including "Can't Go Home" with Steve Aoki and Adam Lambert and "Bonfire" with ALMA. He released "Dance with Me" (featuring Thallie Ann Seenyen) and "Hot2Touch" (with Hight and Alex Aiono) the following year. 2018 saw Jaehn put out his debut full-length effort, I, via Polydor. It was preceded by the single "Like a Riddle," featuring Hearts Colors and Adam Trigger. The next year, he teamed up with English singer/songwriter Calum Scott for the single "Love on Myself," and collaborated with Vize and Miss Li for the song "Close Your Eyes," which reached number 21 in Germany. Several other Jaehn singles charted in 2020 and 2021, including the Top 40 hits "No Therapy" (featuring Nea and Bryn Christopher), "When the Lights Are Low" (with Toby Romeo and Faulhaber), and "One More Time" (with Robin Schulz featuring Alida). Several of these tracks appeared on Jaehn's second album, Breathe, which arrived in October 2021. Subsequent singles included "Rain in Ibiza" and "Do It Better," both of which reached the German charts in 2022. ~ Matt Collar & Paul Simpson, Rovi
