Excellent advice guys
It would probably be easier , Camo, to give you a few labels that specialise in the soulful, deeper house than list a lot of artists.
you can't go wrong with anything from
OM Records, Naked music, Salted music, NRK, Seamless
for the soulful sound.
Try and find something by Miguel Migs, or Jay-J to give you an idea of the sound these labels produce (for me there is no better !!).
As for deeper I highly recommend anything by
Plastic City, Pesto - Dessous - Babayak Shayan.
You might want to try to some of the Hedkandi series, the "Beach House"
and the "Deeper" series are excellent.
good luck
