Rhythmtree is still Rhythmtree.. Since the festival known as Rhythm Tree began in 2010, Widget Productions (UK) Ltd have been the co-producers, technical production team and site designers. Since 2011, Widget Productions have been the sole financiers of the event in it's entirety. 2015 is no different and Widget Productions along with their extended family and friends continue to bring you Rhythmtree Festival at Three Gates Farm, Calbourne, Isle of Wight. PO30 4NA. This year, to broaden the musical horizons of the event even further we are pleased to welcome to the family a new team booking the artists and we think you'll agree that 2015 is going to be the best Rhythmtree Festival yet. We look forward to welcoming you to Rhythmtree Festival.
