Re: UK Underground, Minimal House, Deep Tech
You won't read this on any official websites but this is how many household names got started over the last 20 years in the UK.
Find a venue that's capable of holding 100 but feels good enough with only 30 in, this could be a the back room of a pub, social club, snooker hall. I once went to a great night where the promoters found a curry house not doing that well and persuaded them to clear out the tables and make sure the bar is well stocked.
Team up with 2-3 other DJ's/promoters and put on a free night. If the venue requires payment or you need to rent a sound system, pool your money. The party has to be free to attend, even charging a quid and people won't come.
Make sure someone is on hand for party treats, even if just for an hour at the start. Do not get involved yourself in anyway but this is what your guests want and will be the key to your success. If that person does well out of it, agree a donation to the sound system and decor for future parties
Promote forthcoming parties but don't overdo it, instead make out the previous parties were the best thing ever. Which to be fair, 60 people in a basement, all off it, no security, great music and good vibes all round, usually is.
Keep going for a year, two years. By this time you'll have possibly fallen out with each other or certianly bickering where to take the night next. You'll have got too big, had a couple of moody parties and a few shadey people will have popped up.
By this time you'll have two options, either go legit with your night. Move to a proper venue, entrance fee, bouncers, book keeping, branding etc etc.
Sack it all off and approach already established nights who will no doubt of heard of you by now and salivating at the crowd booking you will bring.
Either way, you'll be on the first rung and after that will depend on your agent, how many bookings you want to do and if you do keep a hand in the promotion side of things - how successful your night is.
After this though make sure every bio and interview afterwards has blurb along the lines of "SB, cut his teeth at the now legendary [Name] club. "Yeah, those parties were immense, a bit amateurish as we learning along the way but you know the spirit was there, we didn't even charge to get in. They were crazy too, if you know what I mean, (chuckles), I'd rather not say too much if you get me, but they were special, special times."
Seriously, that's the blueprint and you can buy me a drink when you're headlining Space.
