Gasolin' (also called Gas 1) is the debut studio album by Danish rock band Gasolin'. It was released in November 1971 by CBS Records. Instead of boogie rock and catchy tunes, they relied on creating songs with a moody feel such as "Langebro", "Fra dag til dag" and "Tremastet beton". The latter is recited by the poet . Lead singer Kim Larsen later jokingly referred to the song as the first Danish rap. The lyrics and the music have a dark and mysterious ambience. From this album "Langebro" was released on the single with "Lilli-Lilli" on the b-side.
