Manhattan Calypso:
The old, less-than-complimentary, genre label was a reference to North American pop's so-called “Brill Building Sound,” 1619 Broadway, Manhanttan. AKA: Tin Pan Alley.

Lord Templar & Manuel M. “Manny” Warner's Monogram, Records (Soundcraft, Supertone et al) were in the lesser known Alden Building a few doors down at 1650 Broadway. Tenants had access to the tiny Allegro Sound demo studio located in the basement. Label hypes & marketing to the contrary, no pressing or manufacturing on site.

General consensus is, the Alden eventually had as much, or more, to do with the Brill Sound as the Brill. Particularly true if one breaks it down by genre, like calypso.
