Some of the albums, such as CAPTAIN BLOOD: CLASSIC FILM SCORES FOR ERROL FLYNN and THE SEA HAWK: THE CLASSIC FILM SCORES OF ERICH WOLFGANG KORNGOLD, were released on CD in the early '90s.
I was delighted to discover that a significant number of these collections were re-released on CD last month, and some were also released last fall. For what it's worth, one Amazon customer review indicates this series is of higher sound quality than the '90s versions. (Update: Be sure to catch Al Lutz's knowledgeable response to the reviewer, indicating "Sony's reissues use the same critically acclaimed RCA Victor Dolby Surround CD masters" as the previous CD releases. There's more info at the link. Thanks to Al -- better known to Disney fans as the proprietor of MiceAge -- for passing on the info!)
One of my favorites in the series is CAPTAIN FROM CASTILE: THE CLASSIC FILM SCORES OF ALFRED NEWMAN. It includes Newman's famous "Street Scene," which was used in numerous Fox films (more here), Cathy's theme from WUTHERING HEIGHTS, and suites from THE SONG OF BERNADETTE, THE ROBE, and of course CAPTAIN FROM CASTILE. The latter includes the stirring "Conquest" march which was later donated by Newman to USC as its fight song. I bought the CD last week so I could enjoy listening to it in my car on my numerous recent trips to Los Angeles.
Some of the other recordings I own on LP are LOST HORIZON: THE CLASSIC FILM SCORES OF DIMITRI TIOMKIN, NOW VOYAGER: THE CLASSIC FILM SCORES OF MAX STEINER, CASABLANCA: CLASSIC FILM SCORES FOR HUMPHREY BOGART, and GONE WITH THE WIND.
One of the other titles in the series features David Raksin conducting his own scores for LAURA, FOREVER AMBER, and THE BAD AND THE BEAUTIFUL.
I'll probably gradually pick up the CD versions so I can load them in my iPod and play them while on the go.
There are several more titles in the series. All are highly recommended to those who love classic film music.
