Working Lives Berlin: Musician
Roger Baptist, otherwise known as Rummelsnuff, worked as a bouncer for many years before he made music his full-time career.
He has over three million hits on YouTube, a record deal and a film in the pipeline. The 49-year-old lives on a former World War Two barracks.
"It's not Beverly Hills," he says as he gives me a tour.
He has an improvised recording studio, and the music he produces earns him just enough money to do what he wants.
"The danger for Berlin, especially inner-city Berlin, is that people move there and because it's a clubbing neighbourhood [they complain] it's too loud, they make reports to the police and the clubs have to close," he says.
"We need a loud inner city otherwise it gets boring."
Rummelsnuff is a mixture of Popeye meets electropunk - mainstream he is not.
Like many musicians, he was drawn to Berlin for its energy, open attitude and affordable rents.
