The mono version of Cream’s Disraeli Gears was quietly released as a standalone a few weeks back. (It was previously available as part of the DG ‘deluxe edition.’)
My memory isn’t what it used to be, but I recall DG as being firmly in the ‘bass over here, guitar over there’ camp that characterized a lot of early stereo – that dry, empty sound.
Unlike some mono, the DG mix doesn’t throw much of a soundfield. What it does do is punch better than the stereo ever did. Jack Bruce’s bass is more prominent and Ginger Baker’s drums aren’t quite so thin sounding.
What I’d like to know: was the mono mix the primary mix for DG? The Beatles’ mono mixes were the mixes the band cared the most about; this, even though it sounds better than my memory of the stereo, doesn’t have the same sense of care about it.
