True fans of the accordion (one of which, I admit, I am not) may disagree with me, but I was never particularly taken with Dick Contino. True, he was very fast on an instrument that, by comparison to almost any other you can name, is awkward and unwieldy (Well, maybe not the bagpipe...). But in that regard, he seems to me to fall alongside the novelty saxophonists of the 1910's and 20's, almost none of whom are remembered now as great musicians. As such, he fit in well with the travelling side show that was the Horace Heidt orchestra. Nevertheless, you can hear many more musical accordionists in almost any good polka or cajun band. There were a few creditable jazz accordionists, including George Shearing, whose work was never less than listenable. I don't think any of them ever would have considered doing to Duke Ellington's "Caravan" what Heidt and Contino do here.
Although this disc was definitely pressed by Magnolia Records Company, Hollywood, the label was rather "Horace Heidt Presents", as suggested by slholzer and announced by the Billboard issue of March 19, 1949, p. 20. It hardly needs mentioning that both label and record company were Horace Heidt's own establishments.
