so far. The first single from the album, "Tanz der Moleküle" ("Dance of the Molecules") had previously entered the charts at number 19 and remained in the German top 100 for 33 weeks, making it the group's most successful single to that point. In early 2007, MIA. competed in the Bundesvision Song Contest with their single "Zirkus" and came in fourth place. On 7 July 2007, MIA. performed at the German leg of Live Earth in Hamburg. During a live appearance in Bonn on 19 April 2008, the band introduced their new song "Mein Freund" ("My Friend"). It was the first single from their fourth album Willkommen im Club (Welcome to the Club) released in September and debuting at number 4 on the German album charts. According to newspaper reports, the band also planned to release that album in an English-language version, which, however, never happened. In the summer of 2009, the band announced during an interview with their official fan club that they would take a year-long break from touring, writing, and recording, beginning 6 September. Upon their return they wrote and recorded a fifth studio album, Tacheles, which they announced in late 2011 and published in March 2012. Ingo Puls left MIA. in 2011 due to undisclosed reasons while the rest of the band was working on the album. The first single from the album, "Fallschirm" ("Parachute") entered the charts at number 11, the highest chart position for any MIA. single so far.

He released an album called "Let's Pretend We're Going" in 2003 and remixed songs for bands he or MIA. are friends with (such as Wir sind Helden, Virginia Jetzt! or Delbo). Lately he has remixed mostly MIA.'s own songs.
