These are less psych than Tame Impala but they would fit nicely in the same playlist. And Weval is excellent, I always recommend them. Definitely one of my favorite artists I've found in the last few years. I tried to do quick sample across their catalog, these aren't even necessarily my favorites. You won't find a bad track, I promise. Hope you enjoy!
