Caroline

Caroline has graced The Rock Cave not once but twice, which means she's either incredibly charming or Mark just keeps forgetting to change the locks. She first showed up for a deep dive into the silky, jazz-soaked world of Melody Gardot alongside Steven, proving she has sophisticated taste and probably owns at least one beret. Then she came back swinging with a full Billy Joel conversation, because apparently Caroline contains multitudes — she can go from smoky Parisian café vibes to Piano Man in the same breath without breaking a sweat.

What we know about Caroline is that she appreciates artists who really PLAY, whether that's Gardot's velvet vocals or Billy Joel's legendary storytelling. She's the kind of guest who makes you feel like you're just hanging out in someone's living room, records everywhere, debating which album is the most underrated. Cave Nation, raise a glass — Caroline is good people, and honestly, we hope Mark loses those locks for good.
