Just seen this on facebook, London 1/6/25. https://www.bassday.eu/ and https://www.facebook.com/profile.php?id=61567163921386   Looks like the venue is Magazine London, next door to the O2 Arena, I've seen the address Ordnance Cres, London SE10 0JH somewhere on the above links. https://magazinelondon.co.uk/   A few names have been announced, but not much more at the moment.   Anyone know anything more?
