Music career

Ski Aggu began releasing music on SoundCloud in 2018. His early work focused on partying, though the tone was darker and more melancholic. Many of these early songs made frequent reference to West Berlin hotspots and popular night clubs, with some critics interpreting his lyrics as prescient social commentary on the daily life of young Berliners. Ritter Lean, a close childhood friend, has frequently collaborated on songs with him.
He released his first single Weißwein & Pappbecher ("Wine and Paper Cups") in 2020 during the COVID-19 pandemic. Since then, he has aimed to release new tracks on a recurring basis. His second song, Super Wavy (in collaboration with YFG Pave), remained his most streamed song on Spotify until the release of "Party Sahne×Party Sahne6 October 2022 · SingleSpotifyYouTube Music (search)Tracklist · 6 tracks1Party Sahne2:182Hubba Bubba2:003Partyticker2:054MAKRODOSIS2:555Acid Kotti2:116Weißwein & Pappbecher2:53" in 2022.
After focusing on club performances in the summer of 2021, Ski Aggu prioritised appearances at outdoor festivals a year later, in Germany and Austria. Among his 2022 appearances were the Heroes Festival in Geiselwind, splash!, Poolbar Festival and Frequency.
For the track "Hubba Bubba×Hubba Bubba8 September 2022 · SingleSpotifyYouTube Music (search)Tracklist · 1 track1Hubba Bubba1:59" released in September 2022, he collaborated with Berlin music producer Southstar. One month later, he released "Party Sahne" ("Party Cream"), which featured producers Endzone and Ericson. The song, which samples the melody from the song "Jerk It Out" by the Swedish band Caesars, reached number 32 on the German Singles Chart. It has retrospectively been characterised by entertainment media as his career breakthrough. A June 2024 profile of Ski Aggu in Sleek Magazine noted that following the release of "Party Sahne" he began to perform in larger venues and receive greater exposure by artists for song collaborations. In November and December 2022, Ski Aggu performed first tour, Aprés Ski, appearing in cities across German-speaking areas of Europe.

In his review of the album, 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."

The reviewer rated the album four out of five stars.
