I can take or leave modern personally.
I like some of the Stafford stuff, Soul Bros Inc for example.
But for me, early 80's mainstream club music, the stuff coming out of speakers in every good jazz/funk club in the land beats what we term 'modern' today, hands down anyway, Sharon Redd, Beat The Street, Patrice Russian Haven't You Heard, Fatback Band etc etc.
Now this ain't modern soul, its just soul end of, and nothing elitist about it too, its all mainstream stuff.
A golden age for the vinyl 12", post disco.
Aid.
Edit: Change, Searching, D Train, Your'e the one for me, Shalamar There It Is, Sharon Brown, Specialise In Love, Eveyln Champayne King, Love Come Down, tons & tons of it, you know the stuff I'm on about.
Keep remembering more great stuff, New Jersey Connection, Love Don't Come Easy, superb.
