Mouth Records was a DIY label. It managed one single recorded at Grannys Studio in South London and mastered at RCA. By Punk band Mouth To Mouth. It featured two tracks, 'Gallery Of Dolls' and 'Life In The Subterrain', both of which were on one side, the other being blank. I haven't happened upon that particular strategy before, but apparently it reduced the cost of making the record. The use of a printing outfit to put the relevant information on to blank white labels, which was also done, was a commoner DIY ploy. Two hundred copies were made, and they were sold in the Rough Trade shop in London. The catalogue number was MT-1 and the record was issued in 1979. Distributed By Rough Trade Records.
