Amazing overview and review thank you Dave, I really enjoyed the background detail

Thanks Dave for good explanation about mastering/mixing differences.

Amazing !

Great review as always, Dave. Thank you for the additional history. I'm trying to remain disinterested in tape because my vinyl interest is expensive enough and I want to ensure my daughter gets a fair to good education. Cheers!

Hi Dave - A very good video - Thank you!

This is one of the most interesting discussions I have seen in a long while. In particular, your challenging of the technical distinction between (re-) mastering and (re-)mixing . The former is often thought to be benign. Of course it isn't.

Excellent explanation.

Great stuff.

I bought the UQHR 45 RPM…it was very noisy the first time I played it. I found out, almost all the copies have that problem. Specially in Blue in green. Its very strange that on this channel there was not ONE word about it. I could send the box back luckily enough.

Keep in mind that the original stereo was mixed down from the 3-track session tapes to a 2-track stereo master, THEN cut to lacquers. The UHQR and Classic Records reissues were mixed down LIVE to the lacquers from the 3-track session tapes, skipping a whole generation. In contrast, the original mono was cut from a separate mono session tape, so the original mono was one step closer to the performance. The original 6-eye mono is great, better than the 6-eye stereo. The original session tapes, of course, wouldn't be necessarily compressed. That flat tape would have been created from the session tapes. I'm going to guess that the forwarding of the soundstage with the tape is that the treble was boosted a bit. That always gives the greater impression of detail as well as pushing the soundstage forward. And regarding the clarity compared to the UHQR and Classic stereo pressings? The latter are two steps closer the original session tapes, and you lose a tiny bit of definition with every added analog copy from the master session tapes.

Thanks, Dave, for the review. If I lived next door to you, instead of asking you for a cup of sugar, I think I would grab my quarter track Revox A77, some new blank tape, and ask you to please transfer your fab “Kind of Blue” tapes to my machine! I would someday like to find a reasonably priced quarter track, 7.5 ips, copy of KOB. Columbia also made them in half track, but both types are scarce, though I think it would have been a popular title to make, and expensive. I imagine they would sound like your 6 eye stereo, but better, and of course quieter, because of their medium. Hope I didn’t give some of your readers any ideas about paying you a visit with their tape machine. Mike (currently in California)

I really enjoyed this video, helped me understand some of the details i've often heard in the recording. I have a recent 180g vinyl re-release, the Mo-Fi 45rpm version, and an early 90's CD copy. Not sure I need / want any other copies, but the UHQR appears in 33rpm, because getting up and down for the mofi one is annoying :)

I don't collect tapes, but I really enjoy the thoroughness and attention to detail of your reviews. I own about 5-6 copies of the album on vinyl including the 45rpm UHQR which is indeed stunning. The 2014 mono by Ryan K. Smith is brilliant as well. A technical question for this video: If this came from the safety session tape (used post 1992), wouldn't this have to be a remix as well? If they had two separate three track machines running during recording and found out years later that the first one was slightly off-pitch, surely a new stereo mix would have had to be created from the tape that was running at the right speed? Or am I getting something wrong - did the tape error occur during mixing rather than recording?

Great review.. Few questions in case you know (1) Since these are made one at a time requiring the source tape to be played each time for every tape , would it be fair to conclude that Hemiolia made a copy of what ever production copy was provided to them to be used solely for continuous playback during copying? (2) I didn't get a sense if these are limited editions or are they indefinitely in stock?

Thanks David! Very interesting with all the details. You don't need to ask if it is the speed corrected or not version. You will find it out rather easily when over the whole course of the song/track the speed corrected vs the non speed corrected will have different total playing time. That is a easy tell if or if it is not, speed corrected version. Thanks again for the interesting video. One thing that I have noticed is in for example the bass (Paul Chambers) in "so what" is sounding very very bad. Not that he is playing badly more that the CAPTURING (or that you pointed out added reverberation effect or whatever ?) of the bass sound is very disappointing. If that is due to the old capturing equipment capabilities or whatever I don't know.. I have a astonishing bass performing system that reviles EVERYTHING in the bass region, and the UHQR 33⅓rpm copy. But Paul Chambers would not be happy with the sound that they have captured of his playing in so what. If he would be able to hear it here. What is your thoughts about the SOUND from the bass in so what ?? Why I ask is because you have the experience and the best formats. And thus is the most sold jazz album and the hit track "so what". And everybody loves and praise that and Paul Chambers but the bass sound is in my opinion SOUNDING well below average! And I just wondering if I am totally wrong or it deserves all of it's praises that it has got and I am the only one that have this opinion!?

Interesting stuff thanks for sharing Dave. I find remixes to be a bit of a mixed bag - generally I do prefer the original mix but just recently I’ve had a few where I’ve thought wow this is how is should always have sounded! I really enjoyed the recent ‘Animals’ remix, and the Steven Wilson remixes of the Jethro Tull catalogue are my new favourite thing with ‘Stand Up’ ‘Benefit’ ‘Aqualung’ and ‘Thick as a brick’ on heavy rotation! I’ll be looking to get several more of those asap. Cheers

Great vid Dave . Thanks! I have my hands full of vinyl, so I'm really not ever going into delve into the reels. I have to ask tho, what does something like that cost? It is really very impressive looking, and I will take your word that it sounds great.

Wow you lucky boy ! I am listening to the 45 uhqr version and that is staggering. I am new to vinyl at the age of 55. It's taken me a month of fiddling with the cartridge, but today I think it has its optimal performance. This is the best so far I've gotten from this album. The decay I'm getting on the piano is blowing me away. Not sure what to get next, maybe " amused to death" what do you think ?

Dave, why isn't the Hemiolia release not available in the USA?

I have a 15ips pioneer re calibrated the whole 9, and i need to play it on a studio quality reel player?

good day can I order a copy from you at 7 1/2 speed? I have "ReVox-B77"

How much was the copy Dave

Ice, nice, nice. Congrats. But €600,00 is an investment. Enjoy it. Cheers Stefan

I find it very, very, VERY difficult to believe that a random Italian company somehow has access to safety copies of seemingly every great US Jazz recording from the late 50's and 60's including KOB.

hi watch alot of the rest who payed out and got them speed not right on high end master reel to reel you get this on some of the tascam dc capstan decks i can be out on used decks i have a otari mtr 12 myself could not get a bigger 1/4 inch deck in my home studio i would have to take the door of just got the otari mx80 in with a inch to spare at front door reel to ree sounds ace it's just the cost of the new tapes is now getting silly i know they used mag net film 3 track for masters bbc had 16mm audio film zonel i have some i made some rollers for the otati mtr 12 wow the audio levels a ace man i will take up to 1./2 tapes plus 16mm film as well
