Pioneers of the subgenre gangsta-rap, who have since the 1990s still been active, are Kool Savas and Azad. Within the genre, they implemented an incredibly explicit, broken and aggressive text, that originally still had much influence from English text elements. This style of rap, after the turn of the century, was implemented by the majority of gangsta-rappers in Germany and is, therefore, a very well respected form on the approach of German gangsta-rap. On the other hand, Savas distanced himself from these vulgar and explicit texts. One of the founding fathers of German gangsta-rap, Charnell, the little-known rapper and martial-arts artist, thematized growing up in the midst of a social renaissance. Gangsta-rap in other countries, that resembled the music of the Rödelheim Hartreim Projekt in Germany, was commercially successful in the 2000s. Germany at the time, however, had few rappers active in this subgenre; allowing certain artists in the Berlin underground-hip-hop scene an opportunity to establish themselves with their lyrics representing a certain hardship acquired through the criminal lifestyle which had previously been popularized. Recognizable names from the underground scene are Bass Sultan Hengzt, Fler, MC Bogy or MOK. Another notable rapper and pioneer of gangsta-rap in Germany is Azad. Although he came from the rural Frankfurt am Main, he was a big reason this subgenre became popular in Germany. In his lyrical text, he thematized the rigid and rough lifestyle of living in the northwest district of Frankfurt.
