The Beatles US and Capitol LPs were plastered with it, especially the earlier ones.
I may be wrong, but as far as I know, only eight songs on The Beatles' Second Album and two on Beatles '65 ("I Feel Fine" and "She's A Woman") had any echo added (plus there was a version of the stereo Rubber Soul with extra echo that was quickly withdrawn and is very rare).
Judging by the frequency of comments to the contrary, the ten songs with echo somehow seem to have blown up, for many listeners, into a kind of false memory about nearly everything on the Capitol LPs being drowned in extra echo. It's not.
Yeah getalife - I have seen this baby ;-) You're right - Sell Out's a good example of Mono/Stereo differences - it gives the songs a completely different feel on each version - and this time there's completely different guitar structures for some of the songs. And what an artefact you have there - give it me!
I've began to notice a kind of loose standard way of presenting mono and stereo versions on mid-60s records. It involves echo.
The Beatles US and Capitol LPs were plastered with it, especially the earlier ones. To emulate the Phil Spector Wall Of Splodge technique, perchance?
On the two versions of "Roger The Engineer", the mono is direct and more punky. You can hear the instrumentation and really can make out how jammy the songs are constructed - the riffs are clearer, and you can hear a kind of demo-quality to the mix; little guitar-string clicks where Beck catches a string with his big-mid-60s-guitar-player finger rings (stay with me on this, folks). There's real aggression on the playing and you can hear how tight a band they were.
The stereo version of "Roger" is more spaced out over the two channels, and misses the directness of the mono mix. Also, there's been added echo across many of the tracks. It sounds a bit washed-out and weak.
Alternately, The Kinks' stereo records are round-about clear to listen to, but they added echo on the mono versions - which to all intents and purposes doesn't help, because they sound like they've been mastered in a bucket of mud. How they got reissued in that format is incredible. The Who's My Generation was remixed into stereo in a very careful way, when they finally gave Shel Talmy the dosh he required - even though it missed some of the original vinyl's overdubbing and guitar parts, it was still done very respectfully and faithfully tight to the original mono version (and I'll state that NOTHING can beat an original mono My Generation - even the UK Virgin 80s reissue kicks butt ;-))
The Stones' Decca output: Ears filled with rice pudding or what? Total splodge. I think the most clear versions are on The Story Of The Stones K-Tel double LP, with crisp mono versions presented. Nice. However, the Rolled Gold double sounds like it has been dipped in a bucket of fudge. Don't know about the 2003 versions though - heard they're much better - got Beggar's and Bleed on the way, so I'll let ye know ;-)
This was picked up in the UK and released in both mono (blue background sleeve) and stereo (yellow background sleeve) versions by Edsel in '83 too. The mono though, had the Happenings Ten Years Time Ago A and B-sides placed as per this track order, and the stereo had the regular track listing (i.e. minus the Happenings A & B).
The mono sounds better than the stereo, and has mixing differences, similar to The Who's Sell Out mono & stereo versions.
Funny that this version compiles a mixed bag of mono, stereo and fake stereo masters...
