I think the Bradford Rios gig was the 2nd time I saw em, but I was mightily kettled for a change and I may have seen em once before (my addled mind lets me down once more), bought NVS just a few days later.
i first heard 54 in a pub, slasher brought the cd in and played you see the light and i was like wow dude who's this so he gave me NVS and the rest is history.
