I know almost nothing, but Backroom Records and Pastries, the Montreal partner involved in this, is within walking distance of home for me. I still haven't been. I'd heard about their pastries actually, then separately about the record store. And now this. They're putting out Washington Phillips on vinyl - and selling pastry - a few blocks away from me. Truly strange. It is literally run out of a back alley shack as far as I know, and so not open this time of year due to the cold.
The fellow running it got a lot of attention a while ago when he found a rare acetate of some of the Velvet Underground's first recordings in different mixes/takes.
