Hello everyone,
I have fixed the audio on the "Linkin Park Live - 2001.02.15 Pittsburgh, Pennsylvania (https://lplive.net/shows/2001/20010215
Originally the audio sounded very low on the video which can be seen here:
I downloaded the audio from the video opened it in Audacity and increased the volume. The audio sounds a bit low quality but that's how it is, however it is now listenable :). You can listen to it here: https://gofile.io/d/3C7om6
Another thing is the LPU15 demo "Attached" can be heard at the end after One Step Closer.
