Hiss is tolerable. It may have come from a vinyl boot.
Sound is pretty nice. Volume is low.
This is just too quite to be an audience. It may be an SB or FM
doesn't sound like a concert .....more like studio outtakes...although someone coughs during the first track.
The second track is actually two tracks....the first one ending abruptly then going to the next one.
