The band assembled in 1927 as the Orange Blossoms, one of several Detroit groups that came out of the
Jean Goldkette office. The band adopted the name "Casa Loma" by the time of its first recordings in 1929, shortly after it played an eight-month engagement at
Casa Loma in Toronto, which was being operated as a hotel at the time. The band never played at Casa Loma under that name, still appearing as the Orange Blossoms at that time. In 1930, the Casa Loma Orchestra was incorporated in New York, with the members becoming owners, shareholders, and board members. The band members were hired on the grounds of "musical and congenial" competence and followed strict conduct and financial rules. Because the band operated as a collective group, as opposed to almost all other bands that had a "leader" for whom everyone worked, the band maintained a stable collection of personnel that varied little. Members who broke the rules could be summoned before the "board", have their contract bought out, and be ejected from the band. The band was led for the first few years by violinist Hank Biagini, although the eventual leader, saxophonist
Glen Gray (1900 – 1963) was from the beginning "first among equals." The complex arrangements called for talented musicians such as trombonist
Pee Wee Hunt, guitarist S. Jack Blanchette, trumpeter
Frank L. Ryerson, trumpeter
Sonny Dunham, clarinetist
Clarence Hutchenrider, drummer Tony Briglia and singer
Kenny Sargent. Arrangements were by
Gene Gifford, who also composed much of the band's book,
Spud Murphy, Larry Wagner,
Salvador "Tutti" Camarata and
Horace Henderson. Gifford's arrangements were credited in large part to giving the band its sound, but even he fell victim to the band's strict rules, being bought out in 1935 due to alcohol-related infractions. 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. In 1943,
Eugenie Baird became "the first girl vocalist ever featured" with the Casa Loma Orchestra. In 2019, the Casa Loma Symphony Orchestra was incorporated and became the new orchestra in residence at Casa Loma in Toronto, led by Catriona Delaney and Paolo Busato and conducted by Maestro Paolo Busato, wholly inspired by the history of this group. ==Radio==
