A music lover from Chicago is digitizing his four-decade collection of live performance recordings and uploading them to the Internet. Aadam Jacobs, 58, began a 40-year concert recording journey at a concert in 1989.

He recorded the entire performance on a tape recorder. Aadam met a friend who also loved music, who suggested that he record these performances so that he could "relive" the live performances later for free on tape.

In the early days of recording, he was often kicked out by some club owners who thought he was secretly recording music and selling it. But it wasn't long before he established a reputation in the Chicago music scene, with many venues even allowing the "recording guy" free admission. His collection spans 40 years and includes rock, hip-hop, etc.

Now, after recording more than 10,000 live performances, Aadam and music lovers have decided to upload these valuable music and cultural materials to the Internet. Each month, volunteers take away nearly 20 boxes of tapes, which are organized, digitized and uploaded by volunteers from the United States and Europe. Subsequent uploads of the music were sent to other volunteers for mixing and restoration before being uploaded to the Internet Archive named after Aadam Jacobs.
