Record Store Day – April 19, this year – has typically brought stacks of collectible rarities and limited-edition pressings, made available just for the day, usually on vinyl only, and only at physical record stores, an endangered species these days. Collectors snap these discs up, and so do speculators: it often seems as if most items find their way to eBay before the day is out.

But as Record Store Day stunts go, no one has an edge on Jack White. Mr. White now runs his own label, Third Man Records, in Nashville, and the label’s headquarters, which he opened in 2009, also has its own record store. Mr. White’s plan for Record Store Day is to produce the world’s fastest record release.

At 10 a.m., he will take the stage at Third Man Records, and will perform – and record – the title track from his coming album, “Lazaretto.” The master recording will then be taken to United Record Pressing, where copies of a 45-r.p.m. vinyl single will be mastered and pressed, while cover art, using photos taken at the performance, will be printed. The discs will be rushed back to the store (they are expected by 4 p.m., possibly earlier) and sold. The plant will continue pressing the discs so long as there are buyers waiting — just, that is, for the rest of the day.
