I guess “ Modern Soul “‘is a subjective term ,but a few I’ve heard out at places like The 100 Club and beyond ….
Jax Transit Authority- Life Is A Miracle ( Covered up as The O’Jays ,and you can see why ,with the “ I Love Music “ style intro )
Doc Peabody - Here Without You - Both Sides ( beautiful mid tempo )
Love Company - Love Tempo ( big on several different scenes )
Fluorescent Smogg - All Of My Life - WG ( Known since the 80’s ,but remained rare ,beautiful falsetto led side )
Melvin Moore - All Of A Sudden ( Sky Hero ) As good as it gets Modern Soul ,known since the early 80’s …
Hope this small list helps ,not played at all Northern Soul venues ,but huge records in the right places
