From YouTube, a transfer of Woody Herman’s band performing Bijou for Columbia records. The recording date is August 20, 1945 (coincidentally Jack Teagarden’s birthday). Bijou is a composition by Ralph Burns, who also composed Early Autumn and played piano with the band.

Bill Harris, who was born in Philadelphia on October 28, 1916, takes the trombone solo. His expressive, slightly quirky, style is perfect for the tune, and Harris became associated Bijou after the recording was released. (Check out the Swing and Beyond website for more on Bijou.)
Early on, Harris picked up other instruments, (tenor sax, trumpet), but he didn’t start playing trombone professionally until he was 22 years old. After that, it’s fair to say his improvising style left a big impression.
Unsurprisingly for a trombonist, some of Bill’s first professional work came in big bands: Bob Chester, Ray Mckinley, and Gene Krupa among them. Employment with Benny Goodman came in 1943 and ‘44. (He’d work with Goodman again in the 50s.) According Leonard Feather’s Encyclopedia of Jazz, Bill also led a sextet at the Café Society (Uptown) in New York City in Spring of ‘44. Woody’s orchestra came next, as Bill became a member of Herman’s so-called “First Herd.” He’d hang around for the “Second Herd” also known as the “Four Brothers” band.
It wasn’t all big-band for Harris though. A notable portion of his career involved an association with Norman Granz’s “Jazz at the Philharmonic” (JATP) series of touring jam-sessions. The concerts, begun in 1944 Los Angeles, often combined musicians of varying stylistic bent, which at the time meant swing players and burgeoning beboppers. For his own part, Harris was essentially in the swing camp, but he had no issues fitting in with the “modernists.” From a 1955 “Jazz at the Philharmonic All-Stars” concert in Berlin, here’s Harris blowing up a storm:
In addition to leading small groups himself, Harris also played the sideman role with other small group leaders, including tenor saxophonist Charlie Ventura, and bassist Chubby Jackson, who was also a member of Woody Herman’s first and second herds. With Charlie Ventura’s “Big Four,” below is “Characteristically B. H.” While the melody is be-boppy — maybe even monkish — Harris mostly floats above the rhythm section during his solo:
During the 50s, Harris often performed and recorded with other Woody Herman alum. Here he is playing Everywhere, a ballad of his own composition, with the “Ex-Hermanites”:
Harris spent some time gigging in Las Vegas before eventually retiring to Florida. He died in Hallandale, Florida, at the age of 56, but not before leaving a significant dent in the jazz trombone universe.
