I'll not comment on the video of your band as its not my place to express an opinion good or bad but if you're getting terrible numbers coming to see you Im afraid that says more about the bands appeal than anything else. As Big RedX says theres a healthy Goth scene across Europe and you should be in a self sustaining band at the very least. The idea of driving 350km for a possible 5 people seems completely pointless. Also I would never allow myself to be the "outside" member of any band whose view counted for nothing, but thats just me. So, in my opinion you would be wise to move on to something more fulfilling and proactive, if, after 2 years the lead singer questions your commitment, thats time to split.
