... and the popular titular Gus Arnheim and His Ambassadors. By 1928, Vitaphone figured you could not get much out of one stationary camera booth lodged at one angle at a stationary act. To get a bit more out of their system they would sometimes use multiple camera booths so they could at least get multiple angles. This was necessary for acts like Gus Arnheim and his orchestra.
In this case the band plays Nobody But You, That Reminds Me of You, and a jazzy rag with vocal accompaniment by the band's tenors. A variety of instruments are spotlighted, and since that requires looking at individual members of the orchestra as well as the band as a whole, multiple camera booths were required.
This short is one of several done by Vitaphone that demonstrated the kind of musical popular in the 1920s that was listened to on the radio or danced to in person.
Gus Arnheim had small roles as a bandleader in early sound films such as "Broadway", "Flying High" and even "Scarface".
