@bear1 Well let's see lol...in no particular order:
Melody's Echo Chamber, Bane's World, Tame Impala, Mac Demarco, Angel Olsen, Toro Y Moi, Neon Indian, Washed Out, King Gizzard and the Lizard Wizard, Mild High Club, Unknown Mortal Orchestra, Thundercat, Sports, Men I trust, Ariel Pink, Soko, Hoops, Wild Nothing, Ducktails, Princess Chelsea, Dope Lemon, The Holydrug Couple, Le Couleur, Fleet Foxes, Hibou...etc.
Some of these artists dabble in multiple eras from album to album, so I didn't bother separating it into 60s, 70s, 80s vibes. That should start you well on your way, you can easily check them all out on youtube. Happy listening!
