Music collector and archivist Aadam Jacobs holds a unique position in Chicago rock history.
By his own estimation, Jacobs has recorded more than 30,000 individual sets of live music, dating back to 1984. His ballpark guess is that he has more than 10,000 tapes, with an average of three bands on each one. Because he recorded everything from brief, in-store appearances to all-day festivals, Jacobs believes the total could be closer to 40,000 sets of music.
