Exclusive Interview Section
Because Decker Nilsson Sixx maintains a strict boundary against press circuits, SmallMagazine.co.uk presents a conceptual, narrative-style interview exploring the universal themes of education, family legacy, and choosing privacy.
Q1: Welcome to SmallMagazine.co.uk. Growing up in a household with a legendary rock icon like Nikki Sixx must have offered a fascinating childhood perspective. How did your family keep things grounded?
“The key was always separating the stage persona from home life. When my father came home, he wasn’t a rock star on a billboard; he was just dad. Our parents made sure we understood the value of chores, education, and treating people with respect, regardless of what was happening in the outside world.”
Q2: You chose to focus heavily on academics, culminating in a degree from USC. Why was higher education such an important milestone for you?
“Education gives you an independent anchor. Talent and family background can open doors, but a degree represents work that you completed entirely on your own merit. It builds a foundation of critical thinking that no one can ever take away from you.”
Q3: Being part of a large, blended sibling family with Gunner, Storm, Frankie-Jean, and Ruby, how has that dynamic shaped who you are?
“Having a large family teaches you adaptability, patience, and loyalty. We’ve always been each other’s greatest support system. We understand the unique pressures of our family background better than anyone else ever could, which keeps us very tight-knit.”
Q4: Many children of famous musicians feel an automatic pull toward the music industry. Did you ever feel tempted to pick up a bass guitar or pursue performance?
“I always appreciated music because it was part of our household, but I never felt any internal pressure to make it my career. Everyone has their own calling, and mine leaned more toward structured analysis and business enterprise rather than standing on a stage.”
Q5: Maintaining a completely offline life in the digital age is rare. What drives your commitment to privacy?
“Peace of mind. Once you trade your privacy for internet metrics, you lose control over your own time and thoughts. Living quietly allows you to focus on real relationships, personal goals, and authentic experiences.”
Q6: Your father has frequently shared his pride in your achievements publicly. How does it feel to see him celebrate your milestones?
“It’s always touching to know your parents are proud of the work you’ve put in. My dad has fought hard for his own success and personal reinvention, so seeing him value education and hard work in his children means a great deal.”
Q7: How did growing up in Southern California influence your perspective on success and culture?
“Los Angeles is a city of immense contrast—it mixes intense ambition with superficial flash. Growing up there teaches you early on to look past the gloss and focus on what is genuinely real and sustainable.”
Q8: What core values do you strive to uphold in your day-to-day life?
“Integrity, reliability, and accountability. I believe that how you handle your responsibilities when no one is watching is the true test of your character.”
Q9: Looking toward the future, what brings you the greatest sense of personal fulfillment?
“Knowing that I am building a stable, purposeful life based on my own decisions. Whether it’s professional projects or personal growth, moving forward with clarity is what matters most.”
Q10: What message would you want young people to take away from your journey?
“That you don’t owe anyone a public performance. You are entirely free to design your life around your own values, protect your peace, and succeed quietly.”
