Huge SFA fan here. Before my huge record cull (which financed a great many bike things of course) I had pretty much everything, even the old ankst 7″s.
I was listening to the last one (dark days, light years) just yesterday and I think it might just be my favourite.
Did you ever check out the ‘spinoffs’? Ffa Coffi Pawb is like the ankst stuff but worse, but Gruff Rhys’ solo stuff is just brilliant. As are his gigs! I also found the Cian Ciaran album recently and it is superb, if nothing at all like his input to SFA.
