Henrik Daniel Berggren was born on 11 November 1974 in Gothenburg, Sweden. He had his first breakthrough with the band Broder Daniel, who were known for their chaotic performances and exaggerated lifestyles. During this time, Berggren fought depression and did not care about his own well-being.

Broder Daniel dissolved in 2008 after the band’s guitarist Anders Göthberg committed suicide. Berggren continued to tour with acoustic gigs, and it was said that he was working on a solo album. He went rather silent after a performance in late 2012.

In March 2017, Henrik Berggren released a single from his upcoming solo album out of the blue. “To My Brother, Johnny” was the first of three singles before the release of his debut solo album, Wolf’s Heart, in May 2017. In the press release for the single, Berggren said:

When I was about fifteen years the bottom went out of me. I suddenly suffered from a dejection for my life and future. A cloud of gray meaninglessness fell down over everything. A person of more clinical mindset than I would call this a depression, and it came to be half a life for me. … Only after I finished 30, I woke up from this hopelessness. Afterwards, this period, and my life setting under it, seemed incomprehensible and a mystery to me. Why should a young person with a life in front of him need to be so dejected? How could I become so self-destructive? If I was unhappy about what opportunities life offered me, why didn’t I fight it constructively? Instead, I let it go out over me and let myself become a victim of this.

Following the singles and press releases, Henrik Berggren participated in multiple interviews. In an interview with Nöjesguiden, he stated that he had been diagnosed with CFS (Chronic Fatigue Syndrome) in 2013:

At first, I tried to get myself reported sick, but that was a full time-job. The only way I could succeed was to first become healthy. But then I decided that I should try to finish the album anyway. … I have the feeling that half of me has gone over to the other side. I’m not fully here, and I cannot really care either. It’s a weird ghost-existence.

Berggren’s anti-sociality lead to him dedicating his life to reading and writing. He stated that he was unsure about whether or not he will create more music after the release of Wolf’s Heart, but his active writing led to him creating more material.
