More prog metal maybe, but have a listen to these guys - [url="http://deeexpus.co.uk/"]http://deeexpus.co.uk/[/url] - their current and previous bass players are both members on here.
I've had a number of attempts over the years at getting prog bands going. Not only do some of the musicians tend to be on the "challenging" side ( ) but even if you get as far as putting a set together very few venues are interested, and if you do get a gig nobody comes to see you!
One of the last prog gigs I saw locally to me (Newcastle upon Tyne) was Pendragon*, supported by DeeExpus (see above). Both bands were utterly outstanding, but there was an audience of about 30 people, including both bands are their "entourages"!
My advice if you want to play prog? Relocate to the continent. Poland, Holland, Germany, even ex USSR states. They love their prog over there!
* BTW, Pendragon hail from the West Country, or at least main songwriter/singer/guitarist Nick Barratt comes from Stroud...
