Black Thursday's were a regular band night, held every second Thursday of the month, at Flow. The events began in May 2010, with the final gig in September 2010. While around 60-80 people attended the initial shows, only around 40 attended the last two. The enevt ceased because the numbers attending became too low to keep the event viable. Black Thursday's were organised by the Hamilton Live Music Trust. Screen printed t-shirts and posters were produced for most events.
