Listening to SIENNA SPIRO’s breakout hit, “Die on This Hill,” feels a bit like going back in time. Her music is steeped in the sounds of the 60’s, with elements of jazz, soul, and pop. There’s something very old-school about her, right down to her aesthetic. With a voice that contains so much depth and texture, she carries a lifetime of emotion packed into every song she sings. For an artist who’s just burst onto the scene, it’s remarkable how big an impression she’s already made.
