Wulff’s musical affections have always been equally divided between pop and jazz, beginning in the basement of her parents’ home. "I spent a lot of time there with my brother playing electric bass, mostly funk and soul," she recalls. "I’ve never understood the different camps of so-called serious and popular music. In my own music, I allow myself to do what I want and what interests me – namely, to play good music with good people. No matter what stylistic label ends up being attached to it."

Independence and spontaneity are also the hallmarks of Wulff’s new project. Hand aufs Herz (Hand on Heart) will be the title of her new album. Quartet, quintet, or even sextet? For Wulff, numerology is beside the point – this time, electric guitars were key: "My band already had two drummers and two saxophonists, and now there are two guitarists as well."

"I’ve never really had a tendency to think about what people expect of me," says Wulff with a certain nonchalance. "There have been some upheavals in my life recently – and in my music too. I’ve always been fascinated by the sound of the guitar. It feels liberating to follow such an instinct."
