What eventually gave in was his voice and he was forced to take a break from touring. During this break, in 2012, he was invited to score and participate in the theatre production of "LUBIEWO-KÄRLEKSÖN" at Gothenburg City Theatre.
Following this inspired digression into theatre OSKAR HUMLEBO relocated to Berlin to finalize his third album "Keep your darkness secret" in Birthmark studio at Funkhaus Berlin. Together with Austrian producer Niko Stoessl (Dave Gahan, Grau) he took the next step in his musical career with bigger, darker productions. The result was a sensuous and explosive collection of songs such as " Someday", "Too young to know" and the title track "Keep your darkness secret".
After what was understatingly a troubled process, including a flooded studio resulting in a years worth of work lost, finally in March 2014 the third studio album was released, followed in the fall by the EP "Black Lillies", featuring apart from the title track covers of Cocteau Twins and Suede songs.
Even before touring had ended OSKAR HUMLEBO had started work on another theatre score, a massive four hour production of "FAUST" with Gävleborgs Folkteater and Gävle Symphonic Orchestra. A dark, morbid and beautiful play performed at a repurposed industrial site.
