Ski Aggu

August Jean Diederich (born 3 November 1997), famously known as Ski Aggu, is a German rapper. He is known for wearing ski goggles.

Early life
Ski Aggu grew up in Berlin-Wilmersdorf. His grandfather is the SPD politician and political scientist Nils Diederich.

According to himself, he lived in Ireland for a while, where he intensively pursued the martial art Brazilian Jiu-Jitsu and eventually became the Irish champion in his weight class. Martial arts also feature in his online presence and music videos in the form of poses.

Music career
Ski Aggu began releasing music on SoundCloud in 2018. His early work already focused on partying, though the tone was darker and more melancholic. Ritter Lean frequently appeared on his tracks.

He released his first single Weißwein & Pappbecher in 2020 during the COVID-19 pandemic. Since then, he has been releasing new tracks regularly. His second song, Super Wavy, a collaboration with YFG Pave, remained his most streamed song on Spotify until the release of Party Sahne in 2022.

After some club concerts from summer 2021, Ski Aggu performed at several festivals in the German-speaking region a year later, such as the Heroes Festival in Geiselwind, splash!, Poolbar Festival and Frequency. For the track Hubba Bubba released in 2022, he collaborated with Berlin music producer Southstar.

He achieved his breakthrough in October 2022 with the song Party Sahne, featuring producers Endzone (music producer) and Ericson. The song, which samples the melody from Jerk It Out by the Swedish band Caesars, reached number 32 on the German Singles Chart. In November and December 2022, Ski Aggu played his first tour, Aprés Ski, in many major cities in the German-speaking region.

On 2 December 2022, Ski Aggu released his debut album 2022 war Film gewesen, which includes four new songs. Yannik Gölz from Laut.de wrote that Ski Aggu has an ear for vibes and knows that he does not have to spell out the impact of his music. Some songs seemed sketchy, but overall, there is "too much good music to ignore," making 2022 war Film gewesen "a quite interesting statement." The reviewer gave it four out of five stars.

On 25 May 2023, the single Friesenjung was released in collaboration with Dutch rapper Joost Klein and comedian Otto Waalkes. The song is a reinterpretation of Waalkes' original and reached number one on the singles charts in Germany and Austria.
