He was also a member of the East German punk band Feeling B. Lorenz has released a solo album named Flake feiert Weihnachten, which consists of covers of popular Christmas songs.

In 1983, at age 16, Lorenz began to play in the band Feeling B with Paul Landers and Aljoscha Rompe, a Swiss singer living in East Berlin.

On special occasions, the band members would get together for concerts at punk festivals, until Rompe died in November 2000 of an asthma attack.

In 1994, Till Lindemann, Richard Kruspe, Oliver Riedel and Christoph Schneider entered and won the Berlin Senate Metro beat contest that allowed them to professionally record a four track demo.

A statement from Sergeant Thomas Radula of the Worcester Police Department stated that Lindemann was simulating sex with Lorenz onstage "using a phallic object that shot water over the crowd".

During a concert in Gothenburg, Sweden on 30 July 2005, Till Lindemann suffered a knee injury when Lorenz accidentally ran into him with the Segway he rides during the performance of "Amerika" ("America").

[3] On 12 September 2008, Lorenz married artist Jenny Rosemeyer, who provided the whistling for Rammstein's song "Roter Sand".

The police managed to identify and capture the arsonist, a 28-year-old male with a criminal record who crashed his car nearby while fleeing from the scene.

"Doktor" came about because at one point he wanted to be a surgeon, but he was unable to study to become one because of his refusal to join the East German military.

However, in the same interview, he stated: "I prefer playing in the USA [over Germany] because the attitude to music is more relaxed [in America]," and also opined that he favored the American city of Seattle when touring.

[10] In a 2019 interview with Metal Hammer, he recalled life in East Germany as "free of trouble and pressure, we all had enough money to live".
