FM Acoustics adds: "In the late 1970s and 1980s new cutting lathes finally allowed mastering records with high-level high frequencies. As soon as this was possible, it was promptly overused and some records were mastered with excessive high frequency levels. By increasing the 10 kHz attenuation these records sound more acceptable."
Another factor that made things worse was that some companies like Columbia and Capitol had different equalisation settings for their 45 and 33 ⅓ albums. Also the Columbia 78 albums released in the United States and Europe had different equalisation.

Update 16/9/11: I have found out that this John Coltrane album is actually a reissue of an older album released under the Prestige label. I also found out from this site (http://midimagic.sgc-hosting.com/mixlabls.htm) that Prestige had used the RIAA curve since the 1950s. So it would appear that this album should be played with the RIAA curve. In that case, it was indeed the mastering engineer's intention to showcase Coltrane's skills and downplay the other musicians.
However, I also found out that my album was cut with the Direct Metal Mastering (DMM) process invented in the 1970s by Neumann and Teldec which has a sonic signature because of the process of cutting on metal instead of lacquer.
From http://www.amr-audio.co.uk/html/faq_ph.html#ref : "The sound from DMM records is often perceived as overly bright and forward. While this is not directly a result of the equalisation employed, the tonality of overly bright DMM records can be made more well-balanced or even handed by gently attenuating the upper midrange and lower treble."
