Mastering in the 1970s wasn’t a creative stage. It was a transfer process. The goal wasn’t to make the record louder than everyone else. It was to make sure it cut cleanly onto vinyl.
A good engineer and producer should be doing exactly those things, in consult with the artist. The mastering engineer shouldn't be sequencing the songs to his liking! Any artist who is putting together a release should be listening to test burns before sending it out to be pressed. We're talking about 15 minutes to load it up into CD burning software, and rip off copies for every member of a group. If it doesn't meet their approval, adjust and burn another. CDRs cost less than cassettes cost me 40 years ago! The third track sounds too loud and harsh... adjust it and listen to another cut while you're driving home. Or put the MP3s on your IPad, listen to them.
Can you imagine if you decided that you didn't like the sequencing of the Moody Blue Days of Future Passed and changed them during the mastering phase? "I needed to swap those two tracks to fit the side length" You would have been canned on the first pass.
50 years ago, you had to be aware of the limitations of a record.. side length, bass level and centering, dynamic range, etc. I remember when Telarc put out the 1812 Overture with the cannon shot. Some system would actually jump (but that was the point.. you needed a good turntable to reproduce it). I've bought remastered CDs (commercial) that the remastering engineer put 2 seconds of silence between tracks that were supposed to run continuously to the next without a break. COMPLETELY ruined who know how many CDs that were produced. I sent CDs to companies that had hum from bad grounds, ticks and pops from transfers from records, speed changes and wow/flutter. It makes me wonder if some of these people even listen to the work they are doing.
I've heard several comparisons where someone sent a final mix to a half dozen "mastering services", and some of there were complete butcher jobs. UNLISTENABLE! In most cases, I would have preferred the original mix to any of the "fixed" versions. Squashed, bright and brash, boomy.
Doug Sax, Bob Ludwig, Bernie Grundman and the like earned their reputations by knowing how to get records to hold as much of the original information as possible, not to make it sound like they wanted.
I'm sure there are good mastering engineers today, but where you might have had a dozen or so really good ones back then (many were tied to record labels), today you can find hundreds with some purchased mastering software and minimal expertise. It can become paint by numbers! LUFS -14. EQ - POP/Rock Max level -0.5dBFS. Run the files through the computer and you've got a consistent master!
Thank you.. no!
