This is Talking Violet‘s ‘Indigo’.

Leading with spacious, hazy chords and singer Jill Goyeau’s floaty vocals and immersing the listener in a subtle but driving performance from the bassist and drummer, “Indigo” feels as haunting as it does invitingly familiar. Nineties alternative is a clear influence here, the song channels shades of Slowdive, Mazzy Star, Smashing Pumpkins and My Bloody Valentine.
