As you probably already know, there's not all that much on Bradley
available on the Web. However, I found an article in "Film Score",
which reprints an article on Bradley from 1939(!) See...
... and scroll down to "5/27/1939 Daily News Music"
Another link you might find of interest is "A TECHNICAL AND HISTORICAL
OVERVIEW OF SOUNDTRACK PRODUCTION PROCEDURE IN AMERICAN ANIMATED
FILM", which discuses Bradley as well as other animation composers.
This article has the interesting tidbit, among others, that "Bradley
tried to avoid the use of sound effects whenever possible, in an
attempt to fill their place musically."
An article titled, "Bum Da Daaa, DaDa Da Dun Daaaa: The Early
Animation Composer" notes of Bradley,
"Over at MGM Scott Bradley had a both enviable and unenviable task:
compose music for the animated shorts being produced there. This was
enviable because of the popularity, both commercial and critical, of
the MGM cartoon stars. Unenviable because after all, Tom and Jerry
films are chase films. Perhaps each has a different setting, but at
. Bradley saw this challenge and rather than 'cartoon up'
his work he took a more serious approach. An orchestra composer by
day, Bradley used much of the same orchestral overtones in his music
for MGM which provided a certain serious, cynical counterpoint to all
of the action on the screen."
And finally, although apparently out-of-print, I thought you'd might
be interested in this link to a CD of Bradley's music...
