Not quite my taste, but I actually heard of them before/found GRIN on Spotify a while ago. And yes, you absolutely should, but I suppose the Berlin music scene is much more vibrant than here in Cologne. More of that? Have I recommended Ideal to you before? And Fehlfarben, mostly known internationally for "Paul ist tot" which was on some Call Of Duty soundtrack.
This was playing at my dentist's as I got makeshift dental crowns... he has great music taste, but I always get that awful toothpaste taste in my mouth when I listen to the song now
