A small independent label. Catalogue numbers suggest that Bum lasted for long enough to issue at least two singles, the second of which was Intravein's, 'Speed Of The City' b/w 'Feel So Sick' (BUM-2; 1978), but googling suggests that BUM-1 may not exist. A picture of the label and a short article on Intravein, who changed their name to The Veins shortly afterwards, can be found here.
