Danny Byrd, High Contrast, Blame, Inside Info, Shock One, DC Breaks, Sigma, Brookes Brothers, Future Bound, Furlonge, Metrik and Camo and Krooked do some nice liquid stuff.
No mate, not at all imo. Hospital is real rush driven energy fuelled liquid, dancefloor liquid if you will.
So it really depends what kind you want mate. Artists I would suggest you look into are:
Zero T
Calibre
Brooklyn
Brother
Naibu
Electrosould System
Paul SG
Furney
Tayo
Hobzee
L.A.O.S
Henree
Sinistarr
Labels to look into would be:
Soul:R
Good Looking Records
Fokuz
Horizons
Spearhead
31 Records
Integral
Liquid V
And thats just to name a few! Once you get the bug for researching labels and artists it becomes an addiction... I hope you don't play on vinyl like me, it gets expensive
