Here is a partial quote from Blake Edwards about the Peter Gunn music.
The complete article is here:
PeterGunn-BlakeEdwards

As creator of the show, I naturally insisted on using live music throughout. In this
case esthetic necessity was implemented by the fact that many of the nation's
greatest jazz musicians are in the Hollywood area—an ideal opportunity to handpick
the most creative jazzmen. To give us the musical background required, we also
needed a composer with roots in the jazz idiom, one who could interpret dramatic
action in the language of modern jazz. Henry Mancini is that composer.

Drummer Jack Sperling and bassist Rolly Bundock state the show's forceful
opening motif, Fallout! The raw-sounding trumpet belongs to Pete Candoli, a
veteran of the Woody Herman and Stan Kenton bands. Dreamsville, which might
be subtitled "a love refrain for hipsters," features a moving alto sax solo by Ted
Nash; his brother Dick can be heard dueling with fellow trombonist Milt Bernhart
on Session at Pete's Pad. Saxist Ronnie Lang, who, in common with most of the
musicians here, is a graduate of the Les Brown band, wields a bulging baritone
on Sorta Blue. Other soloists at Mother's, the nitery where Peter Gunn hangs his
Brooks Brothers jacket, are vibist Larry Bunker and pianist Johnny T. Williams.
