It's been a really long time since I've listened to a song that has a vibe like this. Last time I covered a Bastille track was ~2016, so that'd make it roughly 4 years.
French artist Kaky caught my attention with his debut single "La tête pleine," a super-well-produced song that's almost "too poppy" but manages to stay within that fine line of being an indie original.
He's got a pretty cool Instagram page, so if you're digging this, be sure to check that out.
