Saturday is Record Store Day, when independent music retailers around the country host parking-lot concerts and sell limited-edition pressings of vinyl records, which have made a small but forceful comeback in an age dominated by digital listening habits. But if there's one problem with the vinyl resurgence, it might be this: The machines that press vinyl records are decades old, and no one's building new ones, so keeping up with increased demand is hard.
