just saw the lineup for the Darker Waves music festival in november and its insane, the line up is actually insane. its a lot of alternative 80s/90s bands (tears for fears, B-52s, and the cardigans to name a few) but also some modern bands that have a retro sound to them. (molchat doma, and london after midnight) so the festival looks amazing so far, and it's even right on the beach!!
rock cellar magazine has a good article about it too (the link to it is down below)
