With his background of having been a busy guitarist in Berlin's rock scene until the end of the 70s, Bonni started to use his knowledge of rare records for a brisk trading of LPs. When he opened his "Pandora's Box" in 1984, he soon began to follow a very distinct path: Instead of simply going for fast profit with a run-of-the-mill-type product range, he went for nothing but quality from the beginning: A fine collection of music he himself loves to listen to and which he can recommend with a clear conscience.
