From the legendary Canary Records Bandcamp site:

From the 1910s through the 1950s, immigrants released 78rpm discs marketed to their own language / ethnic groups, and that practice survived for a century well into the era of the 33rpm, 45rpm, cassette, and CD era. But from the mid-50s though the mid-70s some Greek, Armenian, and Lebanese-Syrians capitalized on the bellydance fad by issuing their recordings to a broader American public. While many of those recordings drew straight from the repertoire of pre-existing bands, some of the resulting LPs represented ad hoc groupings of performers that were unique and, in retrospect, interesting.
