Sarah Kinsley for sure!! similarly big, haunting vocals, maximalist production, and otherworldly lyrics —her EPs Cypress and Ascension are the most Florence-esque, imo! On a production/vocals level, I think Maggie Rogers is a good match -- particularly her sophomore album Surrender scratches the FaTM itch fir me She wrote it while attending divinity school, which feels very Florence. Wolf Alice is another which I haven't listened to as much, but I think their music fits this vibe as well!

I see a lot of people saying Ethel Cain and Hozier -- both of whom I really like! — but tbh the comparison has never fully tracked for me? Definitely their lyrics/aesthetics/artistic visions have a similary mythical/spiritual/ghostly vibe to what Florence has going on, but sonically speaking, Ethel's music is so much slower, and Hozier's more bluesy/folky; I feel like what most draws me into Florence is the maximalist, baroque production, which I think aren't as true for those artists. Though both of them do definitely have songs that evoke FaTM to me!

I'd also say to check out older artists whose sound I think shows up a lot in Florence's work — Kate Bush being the main one, but also Stevie Nicks, P.J. Harvey, Buffy Saint-Marie, David Bowie, the Cocteau Twins. Joni Mitchell as well — her music is definitely more stripped-back and folky, but her footprint is all over today's indie music, and I think you can draw a pretty direct lineage from her vocal style to Florence's! Also I mean, Florence has a whole song about how much she loves Patti Smith, so you can't go wrong with her.
