Dave Matthews - Dune

Douglas Payne , who runs an extensive website about all the CTI and KUDU releases, and wrote cover notes for many of the anniversary release/re-masters explains exactly why the album "Dune" was actually deleted from the CTI catalogue in 1977. Payne's website includes an article, by Arnaldo DeSouteiro, Brazil’s leading jazz producer and CTI historian, in where he says:

"David Matthews did a second and last album as a leader for CTI, Dune, an artistically successful project who turned out to be a commercial fiasco thanks to the imprudence of CTI’s legal management. Since CTI had not secured writer Frank Herbert’s authorization to use his novel Dune as the thematic center piece for the album, Herbert filed a law suit against CTI and won, forcing the label to delete it from catalog. For this reason, that magnificent album was never reissued in the USA, although a CD reissue came out in Japan by King Records in 1994."
