Any idea wich record(s) contain the most music in minutes (not the amount of tracks)? Also interesting from a technical point of view, to see how much you can squeeze in before its unlistenable.
From what I've been able to find, maximum recommended is 22 minutes per side, but that can be increased with a loss of quality. I found mention during a brief Google search of records being made up to 35 minutes per side.
i came across this thought, because a william onyeabor compilation is released as single cd/3x12" and on the vinyl is more music ( in tracks and time) as on the cd. obviously because of space, or to give the vinyl collectors something special,because a second cd would be the solution then.
As far as I can , you can press about 10 minutes of music on a 12" record (at 45 RPM) or 13 minutes (at 33 RPM) without loss of volume. Anything beyond that means a compromise between duration and volume/quality. I prefer less than 15 minutes per side, over 18 is too much IMO. However, durations can be longer if the music doesn't have loud bass (some ambient, for example).
Personally I don't like the LP format very much because of that compromise. Luckily most albums are slit on 2 or more 12" records these days. But I'm avoiding any 80s compilations with over 20 mins per side after buying this one: Various - House Hits The B side has 29 minutes of bass heavy house music pressed on it... the record is totally useless, it sounds just awful.
I used to have it. On the back is a blurb telling how they made it. I tried to copy and enlarge it but the resolution isn't there. Quieter tracks were mastered so the grooves are closer together. Louder ages the grooves are spaced wider, naturally.
