As Dead Posey, vocalist Danielle Souza and guitarist Kyle Foster might dress in all black and fill their debut video with skulls, spiders and black cats, but this duo is no goth throwback. Beyond their style (their name is a twist on both withered flowers and narcissism), Dead Posey plays intense rock that is not for the timid. The duo is currently in the studio with ALLIES (a.k.a. Tony F of Eve 6), and their debut single, “Holy Grail,” is already making waves as a bluesy, stomping blast of swaggering vocals, power chords and one seriously infectious, howling hook that will spare no one. You’ve been warned.
