SOUND RATINGS

10

 These are the very best recordings of illegitimate origin. All instruments can be clearly heard, there is an absolute minimum of distortion, and the recording is free of major problems. These are most frequently soundboard tapes, FM broadcasts, etc.

9

 This is a thoroughly enjoyable source, but will have a few minor problems, such as slightly intrusive audience noise. This is still a recording you could play for someone inexperienced in listening ROIOs. Not perfect, but very close. These are often audience DAT clones.

8

 A very good source, but with a few more problems. These may include a narrower dynamic range, more intrusive audience noise, minor tape faults and microphone movements, etc. This is clearly not commercial material, but also clearly worthwhile recording.

7

 These sources could possibly have some major faults. Problems may include cut tracks, more severe tape distortion, excessive LP surface or audience noise, and other problems. The typical vintage audience ROIO sound. Still listenable, but will take a bit of imagination.

6

 Major problems, but still a listenable recording for the properly motivated. Probably to be avoided if it would be one of your first acquisitions representing the group. Some of you might not be able to tolerate one of these for very long.

5

 Fairly dire. Blatant occurrences of many of the problems detailed above. Even patient listeners may soon protest. Only for hardcore collectors, or for those with a personal interest in the date and place.

+ or - Next to the grading means just that. A little better then or worse then.

• - sound quality not verified yet.
• - errors!! Not for trade.
