So...KMBR FM had a Stereo-4 matrix encoder, their announcement (that I only heard part of sometime in 1972) makes more sense now...I always thought it was a little strange that they would make such an elaborate announcement about making experimental quad broadcasts if they were only playing some Stereo-4 encoded LPs.

Evolution only released sampler albums using Stereo-4. Sonic Arts issued only one quad LP, that I know of, and it was SQ.
I hardly think that they released at least 2 EV-4 Records , although Samplers , would diminish the fact that they released any albums in quad.
Sonic Arts released Between six and eight SQ albums in the early 80's.
One item I found very interesting while reading both Audio Magazine and High Fidelity magazine 1970 and 1971 editions....was that DGG Records was recording in quadraphonic starting early in the early 70's . And Shelving the Discrete Masters.
And there is a tie to EV-4 encoding.
When DGG took over The Boston Symphony Orchestra, they were recording almost most, if not everything in quadraphonic, but shelving them.
Tanglewood Concerts , The Boston Symphony, The Boston Pops , etc , were being broadcast locally in EV-4 , and in Syndication to various FM Stations in both the USA and Canada.
Initially they used a EV-4 Matrix Encoder in early 1971 for broadcast and Syndication purposes . And also added later in 71 a Sansui QS Encoder.
They used 2 Ampex quadraphonic Reels , plus one Sony , also quadraphonic.
Additional Recorders were 2 Ampex 2channel Recorders to capture encoded programmers for Broadcast Syndication .
I found it surprising that they also used a 2channel cassette recorder from Advent , as a back up tape as with the 2 Ampex 2 ch Reels.
There is a picture of @ Thomas Mowery discussing the quadraphonic recording with Arthur Fiedler of his Boston Pops Concert, which was to be released on Polydor Records at a later date , in stereo of course.
Although all DGG , and Polydor Quad Master Recordings were shelved and the records released were to be stereo?.........
Pure Speculation on my part , but I wonder if any of the Live Boston Pops albums during this time , may have been encoded stealth either EV-4 , QS .
And Also the SQ matrix that was also adopted by Tanglewood/Boston Symphony Trust In 1972.
Aside from that , The Boston Symphony Trust which includes 4 different types of Concert Broadcasts....were definitely involved with Quadraphonic, both Discrete and Matrix, and can be deemed Quadraphonic pioneers of and in the earliest innovations of recorded music .

The only one I know of, and have, is " A Sunday Concert in the Park", by Willie Bestgen and band. Do you know the other titles?
Many of the DGG and Philips quad recordings, made back then, were released on hybrid, multichannel SACD, and some on DVD-A. Some of their recordings were released on the Pentatone label.
Willie Bestgen , is on Repetoire Records , not Sonic Arts .
I can add a few more Record labels that utilized EV-4 . Most if not all Samplers.
Heath
Magnavox
Sylvania
Zenith
All of which goes to demonstrate that the Electro Voice matrix was a very serious contender.
I read that Peter Scheiber also signed a deal with Electro Voice to share equally their respective matrices developments .
Additionally , after CBS SQ entered the market with their backing of this Record Companies' vast catalog , Electro Voice decided to share information with CBS and released their EVX 44 Decoder . And this decoder was adapted to decode both SQ and EV-4 , so as to still provide Electro Voice some market share , with a major contender.

Clearly indicated on the album cover that Repertoire is a division of Sonic Arts.
Now a little bit of .......Did You Know ?
That Harmon Kardon had a decoder/encoder back in the late1970. Known as the "Harmon Kardon (Orban) Quadraphonic Sound Processor".
It had the capability to create stereo from mono sources and to create Quadraphonic from stereo sources. I'm not certain if that is Robert Orban ,of Beaver and Krause , but it certainly makes timely sense.
That Peter Scheiber signed a deal with Advent and his company Audio Data ...to manufacture Decoders and Encoders with his matrix. It's not known if any were ever made , though.
And that his Sampler vinyl record (of which there may have been as many as 3 versions) contained songs from Walter(Wendy) Carlos , Swan Lake , Blood , Sweat , and Tears , and Simon and Garfunkle's - Mrs. Robinson amongst others supplied by CBS . This is confirmed by Audio May 1970 and on a previous thread for Thomas Mowery , his business partner. Supplied via John Mc Clure , head of CBS.
There was a matrix system in 70-71 known as 'I Q' or "International Quadraphonic".
As well as Sansui QS , Feldman/Fixler EV-4 , Scheiber , Dynaco DY 4D and
JVC CD-4 , all in 1970.
That JVC , 3M , and Astrocom Marlux , had Discrete cassette decks , as early as 1970.
That Bert Whyte (Audio Magazine) managed to obtain 2 Discrete Reels of Columbia's New Quadraphonic releases, one was a Sampler the other a Symphony of Gabrielli.
He was a big advocate of all things QUAD REEL , fwiw.
Vanguard was the first Record Company to release commercial Q4 recordings and the second became Project 3 , with 3 entries , initially.
Discreet FM broadcasts were started by Boston WCRB and WGBH of The Boston Symphony Orchestra in April 70 . A year after they acquired an Electro Voice Encoder Jan-Feb-Mar 1971 , and commenced broadcasting on WCRB with the EV-4 Matrix . Broadcasting Boston Symphony Trust (4 different programes) that also went into Syndication in the USA and Canada.
Sound Systems International or SSI , manufactured a device know as the "Quadralizer" , with 4 microphone inputs , and attached to a tape recorder, you could make your own Quadraphonic matrix tape recordings , the matrix is similar to the Dynaco Diamond.
Kenwood had a Decoder/Encoder amplifier the KA-8004 , matrix referred to as the "Quadrix" , and was supposed to be similar enough to SQ , but also RM, Feb 1972.
Kenwood/Trio went on to support the CBS SQ System , not long after in 1972, with their Quadraphonic Receivers.

Fascinating stuff! Thanks!
Oh ok good to know that it is on the Repertoire label.
FWIW Repertoire Records are now a European label (I think Germany) , and besides releases in Kraut rock , they also cover Prog Rock.
It may not be the same company. I can't tell, from the label on that disc.
No I doubt it is the same Company.
That disc is 2003.

Just thought I'd add a couple of more Record Labels that used EV-4 .
Crest Records
Silver Crest
Golden Crest
-these 3 account for a very large number of EV-4 encoded albums , just checkout The Quadraphonic Discography.
and
Halcyon Records

Once upon a time in the mid 70's I had an Electro-Voice 7445 encoder. Everybody loves big VU meters but except for that it was a pretty ugly box. Knock your knuckles on it & it sounded empty like the Tin Man. Open it up & it had very little circuitry, no IC's just discrete transistors. But that was part of the beauty of EV 4: just a bit of in phase blending of the encoded front chs, and quite a bit of opposite phase blending on the rear encoded chs. QS or SQ by comparison required much more.
Of all the non-separation enhanced decoders I think the EV system was the best. In stereo or encoded it gave what people expected: reasonably wide front left/right separation and good depth in the rear. I bet store salesman back then could play some Enoch Light & Eknock the socks off a listener hearing quad for the first time.
To bad they dropped that scheme & screwed up by releasing the EVX 44.
