I don't have a problem with shitty bootlegs, not every live recording can be direct from the desk. I can even listen to some less than stellar recordings if it's a band I like. But to actually suggest a recording is worth sharing when you can't even pick who the band is because the music level is so low is just weird.
Sites like that one I posted a few weeks back with COC and Testament etc at least rate their recordings, at a glance you can see if the recording is straight off the desk or from other sources. They wont share anything less than a 3 on their scale, but I wont download anything less than a 7, and so far I haven't been let down by sound like I found on that Metal Church one. I downloaded another Testament gig from 2001 from another site and the sound of that is quite good for a fan recording....you can actually hear the music
