Well I hope our site does all that Russ espouses....
Our website (and I would've thought MOST regular local club performer's websites) let's our fanbase know when and where we're playing - simple as that.
We play for a lot of regulars - and DANCERS in particular - so I take the opportunity to list our monthly dates with info on Venue, Dance floor, Times, Location (I include a google map link for each Venue) and what style of music we're playing (if possible) and whether or not it's an "event" night e.g. if we're giving away prizes, if it's a themed show and so on.
For regular Club players, I always thought of a website as a "what we're doing this month" kind of thing - nothing more, nothing less.
The jobs themselves come from our Agents and occasionally from a direct booking from an audience member on the night.
