Melanie Martinez releases her hugely anticipated new album K-12. K-12 marks Martinez’s long anticipated follow-up to her RIAA platinum certified, 2015 debut album, Cry Baby. Produced by Michael Keenan with the exception of one song produced by Kinetics and One Love (who previously collaborated with Martinez on such hits as Dollhouse and Carousel), the album serves as a soundtrack companion to an eerily enchanting new musical film, written, directed, and starring Martinez.
