I usually like the stuff that comes out on Influenza Media, sub-label of fokuz, and they're always releasing music. Liquid Brilliants and Liquid Tones sometimes have some good releases too. Don't forget about Integral either.
So this basically just turned into a list of all the liquid labels minus Hospital huh? Thought I should also mention C Recordings, releases a lot of quality liquid as well.
sonata recordings are a smaller label that put out a lot of liquid vibes I think all of the main ones have been covered here though!
Soul:r is my favourite label for liquid
