Expedition ins O is a 2013 German hip-hop album by Käptn Peng & Die Tentakel von Delphi.

He had produced an album the prior year alongside his brother Johannes Gwisdek [de] (Shaban), Die Zähmung der Hydra.

[2][3] The album has a mix of genre elements;[3] Laut.de described it as a "fusion of funk rock and alternative",[1] while Musikexpress said it "crash[ed] between neofolk and Augsburger Puppenkiste".

[2][3] Frankfurter Allgemeine Zeitung interpreted the album as dealing with themes of humanity's insignificance, and not merely commentary on society, but instead the universe.

[5] Musikexpress positively reviewed the album, giving it five out of six stars, and complimenting the wordplay, calling it a "second masterpiece" from Käptn Peng.

[1][5] Frankfurter Allgemeine Zeitung said the "dilemma of German head pop" was " taken to its presumable extreme" by the album, with the "music and message are so far apart that they almost span a world and meet again at the end".

[4] Langemann viewed the album as not fitting the media's division of German hip hop into either "friendly hipster music" or "vulgar street rap revival".
