Iron Curties – German Beer (ft. Daniel Son) (Video) June 9, 2018 stefanoneder . Video . Daniel Son, German Beer, Iron Curties, Modus Operandi I didn’t realize this cut from Iron Curties album, Modus Operandi, was given the visual treatment? I just shared it as a single but let me get this song with Daniel Son out again because it’s that kind of dope. Don’t front and check the album.
