Leave that band.
I had a similar situation with a couple of members (the band only really had me, a bassist and a vocalist since the drummer, who also never did anything, injured his shoulder). I wrote all the material, tabbed it out for them (and they never bothered to learn it), held their hands in learning stuff, recorded the stuff I'd written for the band on my own and they never lifted a finger. It was only even a band in name.
So I scr@pped it and took the stuff I'd done, put it under a different name, called it all and instrumental solo project and carried on basically exactly the same without them.
If, by some miracle, I find some people that
- like the music
- have interesting musical tastes and contributions to make
- are able to play the material (some of its a bit tricky)
- can and will put the effort in
Then maybe it'll be a band again, but for now its me, a handful of guitars, a couple of amps, a few mics, a PC, an interface, a DAW and 50 gigs of drum samples. Gigging is out, obviously, but I'm much more musically productive and happy without having to think about dragging lazy gits (who I love to bits btw, they're awesome guys and very good friends, but they're $%&#ing useless) along with me.
I cant help but note that you have basically the same resources, and seemingly similar interest in getting a bit creative with them, maybe take some time to focus on that, then use that to find committed and compatible members (which surely must be easier in london than west cumbria?)
