Swamptrash were a Scottish bluegrass/psychobilly band formed in 1987 in Edinburgh. They split in 1990 and several of the members went on to form Shooglenifty. The band has been recognized as crucial to the development of experimental Scottish acoustic music.
they really were a ramshackle and thoroughly enjoyable faux-punk string/bluegrass band who attacked new and old tunes with the verve and self-evident pleasure others heard in the Pogues
