If John Mayer’s sixth album ‘Paradise Valley’ was already met with rave reviews, it’s third official single “Who You Love” will surely take the album to new heights. Featuring the reigning #queenofpop Katy Perry, “Love” is possibly one of the best love ballads ever written. Last week, a photo shoot of the couple by noted photographer Mario Sorrenti surfaced online and it’s everything I could’ve ever asked for. It’s already great enough that ‘Prism’ continues to dominate the charts and radio. But showcasing one of Katy’s true hidden talents (her #natural side) while showcasing true love is just beautiful. And now, with the release of Katy’s best (and most meaningful) vocal to date, both projects will soar. The harmonies between these two alone is simply beautiful. And Katy’s ad-libs at the song’s end (beginning at 3:35) are Grammy-worthy. “Unconditionally” may be a slow-burner on the charts, but both singles out will make for a winter long chart run for both artists.
