John-Lewis plays cheerful Dutch folk songs on his guitar about the heartache of life, with influences from funk and blues. On stage, he's uninhibited and completely in touch with his audience, as if they were together in a pub. At the same time, this conviviality clashes with his mournful lyrics. John-Lewis sings about love, everyday pain, and the times he's had one too many. His music is a personal outlet that resonates with the zeitgeist.

His debut EP, "Vals Licht," will be released on May 22nd, and John-Lewis is celebrating it in style in the Upper Room of Paradiso. This EP reflects on themes like addiction, love, and the mind—typical topics you can't miss during a good conversation in a pub. John-Lewis gives the audience a glimpse into his story and makes them familiar, a longtime friend. The show evokes the warmth of a living room, the coziness of a pub, and the intimacy of therapy.
