A Chicago concert superfan Aadam Jacobs who has recorded more than 10,000 shows since the 1980s is working with Internet Archive volunteers to digitize the collection before the cassettes deteriorate. "So far, about 2,500 of these tapes have been posted on the Internet Archive, including some rare gems like a Nirvana performance from 1989," reports TechCrunch. From the report: For many of these recordings, Jacobs was using pretty mediocre equipment, but the volunteer audio engineers working with the Internet Archive have made these tapes sound great. One volunteer, Brian Emerick, drives to Jacobs' house once a month to pick up more boxes of tapes -- he has to use anachronistic cassette decks to play the tapes, which get converted into digital files. From there, other volunteers clean up, organize, and label the recordings, even tracking down song names from forgotten punk bands. The archive is available here.
