Released in 2009,
Sido's fourth studio album,
Aggro Berlin, is named after his record label, which was put to rest that same year. Highlights of the 22-track album include the Top Five hit "Hey Du!," plus the follow-up singles "Geburtstag" and "Sie Bleibt." There are collaborations with
Samy Deluxe,
B-Tight & Alpha Gun, among several others. The album closes with "10 Jahre," a reunion of Die Sekte, the rap group with which
Sido got his start. ~ Jason Birchmeier
