Hi Daniel,
London can be a bit thin on the ground for publicised techno events..

Dave the Drummer and Jerome hill generally play at very underground events in London, that is if they have no gig elsewhere...

Rumour has it @ Dust in Sheffield (150/200 km north of london) there is Neil Landstrumm LIVE and Mark Hawkins DJ on 25th July

Currently we are trying to book dates for Jerome Hill in Germany, so if you don't get to hear him this time, maybe you will be able to soon closer to home...

I'm not sure when Michael Forshaw will next play in the UK, I think maybe in June, he has a residency at Monox in Glasgow though every 2 months...

Hope this helps!
