Julian...I tried forever to start more of a straight ahead heavy blues rock band for years. Just based off the experience that whenever I tried to do anything with "metal" in the title, I just got a bunch of guys whose biggest influence was Disturbed or wanted to play black metal (that's more recent). The problem with my plan was I ended up getting ambushed into playing 12 bar blues with people who could barely play and never wanted to use distortion A LOT. I would still do that though, I still really dig classic rock, southern rock and the branches of these genres that would be probably just be radio rock if they came out in the 70's. Still love extreme metal stuff too, it just seems nearly impossible to get going here at all and driving far to find it I'm still stuck with the same typical band BS everyone in the Band Management subforum complains about.
I've had similar problems with finding people to play with. It seems the only people that have the same mentality as far as large amps (half stacks, full stacks) are 'metalheads', but like not the good kind of metal (screaming, thrash-derived, etc, etc), and all have Mesas (not that I'm knocking Mesa, but not my favorite sounding amps). And people that are interested in the genre I lean towards (which I've settled with refering to as Acid Rock, essentially the heavier side of psych, Hendrix, Cream, etc) are pretty set on using small Fender combo amps and big bloody pedal boards. I just want to find some guys into using Marshall plexis (or similar) with a minimal pedal board (fuzz, wah, phaser/univibe). The problem is is most people my age (that's a played out trope, isn't it?) seem to think what I'm playing to "too angry and metal" and unnecessary to use anything more than a 25w amp, since 'rock' has become such an apparently wimpy shadow of its former self. But I'll gladly play with older guys in blues bands because at least they can do some soloing instead of just playing choppy chords and calling it rock. I mean, you think blues players like clean? You should hear what a lot of guys in bands I see at school are aiming for. Telecaster (or Jazzmasters) into fender combos with like no distortion, just comping simple chord progressions, with straight 8 bass lines. Gimme a blues band or cover band any day of the week over that.
But I get what you mean about using heavy blues rock as a descriptor though. I usually describe what I play as heavy psych blues, but that's why I've switched to using Acid Rock as a description because when people hear blues they think of old white dudes playing in bars just doing the same bloody 12 bar progression over and over with slightly different lyrics.
And band management? Don't even get me started. Maybe it's just what I got used to playing with older guys when I started playing out, but I got very used to a fairly business like way of running a band. Democratic, but no nonsense, as in we will play this song over and over in rehearsal until it's nailed down, and everyone should have a decent concept of how the song goes before arriving at practice. Right now, I'm playing with some decent players, but they haven't really played in bands before, so it often feels like I'm pulling everyone along, and have to teach them the song structures and everything at the practice. And then there's always the guy suggesting songs way out from left field. Not that I'm opposed to incorporating a myriad of influences, but suggesting songs that would be pretty difficult for a 3 piece power trio to pull off and are totally outside of the scope of what we're aiming at just ends up getting tiresome (yes, we can incorporate some funk into this psych jam, but a full cover of Flashlight by Parliament, including bringing in a 3-piece horn section for a single song, is not really in the ballpark).
