Cannot say much about this East London band that has not been said better elsewhere. For about three years, they breathed new life into punk rock in the UK, are generally credited for the name given to a new breed of stripped down, working class punk rock.
Here are the two John Peel sessions recorded by the band in 1979 and 1980.
My copy of the 1979 Peel Session is in mono. Here is a youtube link to a much better copy:
