Soul Limbo had reissues past 1975 (was reissued in the US in 78) which Storf said this one hasn't been reissued since then. Other albums that loosely fit:
Booker T - Doin' Our Thing - 1968, reissue in 1970
Otis Redding - The Immortal Otis Redding - 1968, repressed in 1975
Albert King - King Does The King's Things - 1969, reissued in 1970
Soul Children - self-titled - 1969 but no US reissue since that year despite multiple pressings in 1969
Eddie Floyd - You've Got To Have Eddie - 1969, no reissue past 1969
Booker T - Uptight soundtrack - 1969, no reissue after 1969 in the US
Carla Thomas - Memphis Queen - 1969, repress in 1975 but also had one in 87 in the US
Mar-Keys - Damifiknow! - 1969, reissue in 1971
Johnnie Taylor - The Johnnie Taylor Philosophy Continues - 1969, not re-released after that on LP but was repressed in 1969
Jimmy Hughes - Something Special - 1969, no reissue on LP past 1969 (was reissued in 1969)
Guessing as
@keylime_5 said, it's likely Otis - The Immortal Otis Redding, which is a shame because I already have an OG press of it...but would maybe double dip if I don't like the other ROTMs. It is a great album though!
