Effective period / Period of releases: 1978

Before 1977 was out, this "Dimensional Sound" group was replaced by another hack soundalike group, "Dynamic Sound" . Ads circa 1977-8-9 on local New York radio stations inviting would-be singers to put their voices on pre-existing instrumental demo tracks at a recording studio which may have bore the name(s) of one of these "soundalike" acts, it is probably the case that those would-be "demo" singers were the ones heard on these recordings.
