Anyone remember, or even hear of, a label called FORTISSIMO produced by
Riverside in 1961? Super-quiet surfaces (wonder how they managed that?
Riverside never turned out a quiet disc in their lives), discs cut from the
inside out (changer owners must have loved that), master tapes recorded at 60
IPS "with the heads oriented horizontally" (whaaaaa..?), a 400hz alignment
tone, and repertoire such as Racing Cars, Jets, Pipe Organ (miked from inside,
I think) and Banjo Polkas.
Amazing what turns up in some of these old audio magazines that I've never run
across in over 45 years of record collecting.
