After a hiatus of five months, Kenton formed a new, larger ensemble to present Concerts in Progressive Jazz.
This goal proved mostly obtainable but the band had to still fill in its schedule by booking dances and movie theater jobs, especially over the summer.

Pete Rugolo composed and arranged the great bulk of the new music; Kenton declared these works to be Progressive Jazz.
A student of famed composer and educator Russ Garcia, Bob Graettinger wrote numerous works for the band, starting with his composition Thermopylae.
His ground-breaking album City of Glass would be recorded by Kenton; works created from 1947 to 1949.
Ken Hanna, who began the tour as a trumpet player, contributed a few compositions to the new band, including Tiare and Somnambulism.
Kenton contributed no new scores to the Progressive Jazz band, although several of his older works were performed on concerts, including Concerto to End All Concertos, Eager Beaver, Opus in Pastels, and Artistry in Rhythm.

Cuban inflected titles from the Progressive Jazz period include Rugolo's Introduction to a Latin Rhythm, Cuban Carnival, The Peanut Vendor, and Journey to Brazil, and Bob Graettinger's Cuban Pastorale.
The addition of a full-time bongo player and a Brazilian guitarist in the band enabled Kenton's cadre of composers to explore Afro-Latin rhythms to far greater possibilities.

The Progressive Jazz period lasted 14 months, beginning on September 24, 1947, when the Stan Kenton Orchestra played a concert at the Rendezvous Ballroom.
And it ended after the last show at the Paramount Theatre in New York City on December 14, 1948.
The band produced only one album and a handful of singles, due to a recording ban by the American Federation of Musicians that lasted the entirety of 1948.

The lone record, "A Presentation of Progressive Jazz," received a 3 out of 4 rating from Tom Herrick in DownBeat.
Metronome rated it "C" calling it a "jerry-built jumble of effects and counter-effects" and "this album presents very little that can justifiably be called either jazz or progressive."
Billboard scored it 80 out of 100, but declared it "as mumbo-jumbo a collection of cacophony as has ever been loosed on an unsuspecting public.

Many sidemen from the Artistry band returned, but there were significant changes.
Laurindo Almeida on classical guitar, and Jack Costanzo on bongos dramatically changed the band's timbre.
Both were firsts for the Kenton band, or any jazz band for that matter.
The rhythm section included returnees Eddie Safranski (bass) and Shelly Manne (drums), both destined to win first place Down Beat awards.

Four of the five trumpet players returned: Buddy Childers, Ray Wetzel, Chico Alvarez, and Ken Hanna.
Al Porcino was added to the already powerhouse section.
Conte Candoli joined the band, replacing Porcino, in February 1948.

Kai Winding, star trombonist of the Artistry in Rhythm band would not be a part of the Progressive Jazz era, except for a few dates on which he subbed.
Milt Bernhart came in on lead trombone.
And Bart Varsalona returned on bass trombone.
Bernhart's first big solo with the Kenton band proved to be a major hit, The Peanut Vendor.

The saxophone section was much improved and modernized.
Returning saxophonists included baritone Bob Gioga, holding down his chair since the very start, and Bob Cooper on tenor.
With Vido Musso's departure, Cooper and his modernist sound became the featured tenor soloist.
Art Pepper came on as second alto, the "jazz" chair.
And the new lead alto was George Weidler.

This was literally a band of all-stars.
They received five first place awards in the Down Beat poll at the end of 1947, and similar awards from the other magazines.
The arrangers continued to push the limits of these superb instrumentalists in their compositions.
Works from this period are more sophisticated than those written for the Artistry band, and are some of the first and most successful "third stream" compositions.

The band criss-crossed the country, appearing in the nation's top concert venues, including Carnegie Hall, Boston Symphony Hall, Chica
