Tonight (May 7th) at 10pm (US East Coast time) the LP Lounge will be featuring 2 complete vinyl LPs - the catch - these recordings were mixed for LP release, and are unavailable in any other form. They were part of the #Quadraphonic revolution that came (and went) in the 1970s. Even though 5.1 and other forms of surround sound are fully accepted standards today, both in Movies and recordings; in the 70s it was a niche market. And even though all quadraphonic LPs were playable on just about any regular stereo system, the record companies reverted back to the early days of consumer stereo (when you could buy an album in stereo or mono) - and issued most quad releases in both stereo & quad versions (the quad costing $1 more per LP).
To be fair, most of the reissues, and many of the new albums were mixed for stereo, and had to be remixed for quad. When the CD world opened up, and the old albumss became available in the digital domain - it was the original 2 channel stereo masters that were used. As a result - the only way to hear the mixes used on these LPs, is to track down one of the LPs - which we have done for you. Be there tonight on RadioMaxMusic.com!
 
Only 50% true. As many here know, the Art Garfunkel album has been re-released on 4.0 SACD by Dutton-Vocalion. The next Garfunkel album, "Breakaway" was also re-released on 4.0 SACD at the same time.

the mix used for the sacd is the same as that used for the Q8 - but the LP mixed the rear channels into the front, out of phase and 3db down -
while the sacd is the way to listen to this - it's not the same as the SQ mix. which can only be heard on the original LP.
 
The SQ LP and Q8 share an identical (intended) mix, it's simply that the limitations of the SQ format do not allow for a completely discrete result.
Had SQ been able to produce a discrete result, then the SQ LP, Q8 and SACD would all share the identical 4-channel mixes.

So, essentially, due to the limitations of the SQ Matrix, I suppose you could conclude that it is a different mix. However, it is not supposed to be.

But, if we're going to compare apples to apples, the Stereo LP and SQ LP mixes are different.
 
So, aside from the source origination discussion, I wonder how the broadcast went?

Did you get good reactions Bill?
