It was released in 2003, and contains the original seven studio albums they released between 1971 and 1977, the live album, Live sådan (but for some reason not Live i Skandinavien) and Additional tracks.

Several other rare tracks such as "Endelig jul igen" and "Where Do We Go Now, Mon Ami" are for some reason absent.

The Black Box was a big seller and confirmed that Gasolin' is the most popular rock band in Denmark ever.

In 1981 A Box Full of Gas was released containing Gas 5, Efter endnu en dag, Gør det noget and an EP with these songs: "Marken er høstet", "Skru op", "Som et strejf af en dråbe" and "Det er en kold tid".
