After a blast of guitar feedback, 22-year-old Kurt Cobain politely announced to the crowd at the small club called Dreamerz: “Hello, we’re Nirvana. We’re from Seattle.” With that, the band, then a quartet, launched into the riff-heavy first song, “School.”
Jacobs surreptitiously recorded the performance, documenting the fledgling band in raw, fiery form more than two years before Nirvana’s global breakthrough with the album “Nevermind.”
Jacobs went on to record more than 10,000 concerts, with increasingly sophisticated equipment, over four decades in Chicago and other cities. Now a group of devoted volunteers in the U.S. and Europe is methodically cataloging, digitizing and uploading them one by one.
