hush has an upstairs / downstairs for new r&b and oldschool r&b as far as im aware. Canton Bar played some stuff but i think due to floor plans and what not they can't keep trading anymore.. complaints or something about the property.

Metro City's R&B lounge has always played oldschool music, always recall biggie being played.

Haven't been out in months though so I'm not sure what is being played these days.
