In 2016, the vinyl information and e-commerce site Discogs.com broke its own most-expensive LP-sale record twice. In March 2016, David Bowie's David Bowie went for $6826. That post-Bowie, death-related purchase was then topped when the next rock star fell. A month later, in April, a copy of Prince's Black Album, the grail of his catalog, went for $15,000. In recent days, however, the record was broken again when a test pressing of cult guitar hero Billy Yeager's 301 Jackson Street, one of just eight ever made, went for $18,000.
