However, from 1957 to 1963, it re-emerged as a recording session band in Hollywood, made up of top-flight studio musicians under the direction of its most notable leader of the past, Glen Gray.

[1] Arrangements were by Gene Gifford,[1] who also composed much of the band's book, Spud Murphy, Larry Wagner, Salvador "Tutti" Camarata and Horace Henderson.

The band's manager, Cork O'Keefe, was made a vice president in the corporation and arranged bookings in venues such as Glen Island casino, which they helped popularize, and the Essex House Hotel, that led to their increasing fame via radio broadcasts before and throughout the swing era of 1935–1946.

[citation needed] Their mid-1930s appearances on the long-run radio comedy-variety program, the Camel Caravan (introduced with their theme, "Smoke Rings") increased their popularity.

Gray chose not to conduct the band in the early years, playing in the saxophone section while violinist Mel Jenssen acted as conductor.

For a time, during this period, the band featured guitarist Herb Ellis, trumpeter Bobby Hackett, pianist Nick Denucci and cornetist Red Nichols.
