Although this orchestra was popular in his day, I hardly found any information. Dismuke.org writes: "Joseph Knecht's Waldorf-Astoria Dance Orchestra and Yerkes Jazarimba Orchestra were two of the more popular dance orchestras on the Columbia label in the late 1910s. Musically, the era was a transitional period when ragtime was on the verge of being replaced by jazz as the dominant force in American popular music. It wasn't until about a half decade later when the jazz influence was more firmly entrenched.". This great record was made in 1921.
