Does anybody know where I can find old r&b/soul/funk acapellas that acts like Bachelors of Science use as the vocal parts of their tracks? I've already tried googling it, and I was looking for a particular acapella ("United" by The Intruders) but all I found was an instrumental, and I don't know how to get an acapella from an instrumental. I love the feel that the oldies give to liquid funk songs. They just make them sound much more sincere. Also, could anyone suggest good, old r&b/soul/funk songs for me to listen to? So far, I haven't been very successful in incorporating vocals into my mixes. Thanks for the help.
