I like them and have since I was given two tracks ('The Opening' and 'We Have This Place Surrounded'live in Amsterdam a couple of years ago or so). I really enjoy 'Exits' which manages to create the stirring sort of atmospheric rock I find lacking nowadays ('Lay Me Down' is fucking beautiful).
I haven't heard 'Union' that much but I can identify at least three tracks that I already really like. The vocals outstandingly emotive at times. Should be a pretty big British band (the sort that do what Coldplay try to do, but properly), but are unknowns to most people.
