I'm sure you would've seen it from D-V by now if it were controlled by Sony, but the Grover Washington back catalog is owned by UMG, who seem to work at a much slower pace compared to Sony when it comes to licensing reissues.
When CTI's self-distribution scheme fell apart in 1974, they signed a deal with Motown to distribute their music (which is why some CTI Q8's have a circular white sticker on them that say 'Distributed by Motown' on them) but relations between the two companies quickly soured and I think less than a year later they were both suing each other. By the time the dust had settled CTI was bankrupt, so the judge awarded Motown (where Washington had signed after leaving CTI) the rights to all of Washington's CTI/Kudu albums (including Soul Box) in lieu of financial compensation. I think after that he ended up turning around and suing both Motown and CTI to be released from his contract (basically saying that their squabbling was ruining his career) after which he signed with Elektra, where he really hit it big with Winelight in 1980. Anyway, I digress - Motown was sold to MCA in the late 80s, then MCA was was sold to PolyGram a few years later, who were then bought by Seagram, who renamed it Universal Music shortly after that.
Just as an aside, the same financial chaos at CTI that saw them lose Grover Washington's masters also allowed Bob James to recover ownership of his four albums for the label, as per an article in a 1978 issue of Billboard:
NEW YORK - CTI Records has apparently forfeited its ownership of four Bob James masters through a combination of events that ended with a federal judge deciding CTI had breached its contract with James and must deliver the masters and all out-takes to him "forthwith."
Judge John J. Galgay, who also is handling the reorganization of CTI under Chapter XI of the Bankruptcy Act, dismissed CTI's contention that it withheld James royalties because CBS Records, which distributes James' Tappan Zee label, had itself withheld monies due CTI on James' "Head" LP because CTI owed CBS' pressing division money.
Galgay ruled that James' 1977 contract with CTI governing ownership of the disputed masters provides that "any failure or refusal" to pay James' royalties within the time specified in the contract "automatically triggers the default provisions."
The dispute began prior to CTI's bankruptcy filing Dec. 8. 1978, when CTI's Jack Hauptman, on Aug. 29, 1978, asked for an accounting of royalties on the "Heads" LP, which CTI was entitled to under the 1977 agreement.
The next day, however, Hauptman followed with a letter saying that although James himself was due $2,732.51 on Sept. 1. no payment was being sent because CBS was refusing to pay "Heads" royalties due to a prior debt CTI owed to Columbia Record productions for pressing CTI product.
"Thus," says Judge Galgay, "according to the terms of the contract, CTI was in default," despite the fact CTI forwarded a check for James' royalties on Sept. 11 in an apparent change of heart that came too late.
CTI says it will appeal Galgay's decision.
Under the terms of the 1977 agreement, however, James must still pay $25,000 in order to get his masters back, the judge adds.
James is also entitled, the court says, to buy back whatever inventory remains in CTI's possession.
The Masters involved are for four LPs entitled "Bob James I" through "Bob James IV".
Amazing to think how much money those albums (which are some of James' most well-known work) have probably garnered for him since 1978, and that he was able to get them back over a tiny overdue debt ($2732.51) that CBS tried to pay 10 days late.
