RSVP for limited presale tickets. Presale: Friday 25th September at 10am General Sale: Friday 25th September at 12pm ~~~~~~~ ELECTRIC BRIXTON PART 2. My 4BY4 show is now fully sold out but guess what.. We’ve gone and added a second date, but this time we’re switching it up and jumping into the SOUNDZ OF LONDON. Expect the full range of LDN’s most important and influential genres, and a fitting line up of artists that paved the way for them.. It’s going to be historical.
