The phrase identifies unauthorized recordings of the 1985 Live Aid concert, specifically in the MP3 format with a 320kbps bitrate, implying a high-quality audio file acquired through unofficial channels. Such files represent audio content that wasn’t released commercially and is distributed without the permission of the copyright holders.
The historical importance of the Live Aid concert, aimed at famine relief in Ethiopia, contributes to the desirability of such recordings. Availability allows enthusiasts to access performances and moments not officially available, offering a more complete concert experience. However, obtaining and distributing such files raises copyright infringement concerns, since those audio files not being officially permitted, are done illicitly.
