Top contenders would be REM and Woodstock mono. The REM release is getting hit all over the place in these forums for it's poor sound quality, although it shouldn't have come as a surprise. Then there is Woodstock mono. I took a gamble on this one and regret it. Ok, Ritchie Havens sounds good and John Sebastion too (not brilliant but good) , but Canned Heat is appalling. Grim! The sound is unbelievably muffled. I have yet to listen to the rest of the album as I couldn't bear it. Expensive mistake. The label on the cover gave somewhat of a warning but what I heard was criminal. Is this the best we can expect for a 50th anniversary release. If you think any other RSD releases deserve a big thumbs down then please post.
