Few artists have polarized as much in recent years as Sun Diego. With his musical vision, he modernized and shaped the sound of German rap, revolutionized the battle culture with his second career as SpongeBOZZ, and established himself as one of the most successful rappers in Germany. But who is the man behind the mask? For the first time, Dimitri Chpakov tells his entire story. He shares about a difficult childhood marked by his criminal stepfather, his time on the streets, poverty, gang crime, and his own sense of hopelessness. A story about the Russian mafia, Arab extended families, psychopaths, and knife fighters - and the love for music. Yellow Bar Mitzvah describes the commitment to a vision and the struggle against his own demons that led Sun Diego to the top of the German charts.
