If I ever do a band with elevated expectations again, and the chance of that is quite low,
in addition to many of the excellent suggestions already posted I'm going to:
1: First recruit a booking agent/business manager/road manager who isn't a player to deal with all the B.S.
Someone like a Peter Grant if the mold wasn't broken. Someone on
my side...
2: Recruit a sound person/tech coordinator who is not a player in the band to deal with the sound reinforcement nightmare scenarios,
deal with the local sound crew, and who can properly mix/operate the monitor system.
Ideally the band would be self reliant to the point of providing a single stereo/5.1 signal to the FOH and the
overall sound would be controlled by someone who is both familiar with the material and is actually motivated to make it sound good.
3: Recruit a superior drummer. This can make or break a band.
As has been stated many times in this thread, everyone involved needs to have the same level of commitment
or else things can turn sour quite quickly.
Here on my own Fantasy Island, I remain a solo act for now and the immediate future...
