Is she a band? Is she a person? We're still not always clear, but from what we understand, the band that was Plumb became the woman that is Plumb. Either way, it means Tiffany Arbuckle Lee, who professionally goes by that name, is belting out thoughtful pop-rock that'll leave you wanting more. Need You Now follows an extended break, with more than five years between albums, but she's far from out of practice. Case in point: "I Want You Here" is a moving "miss you" to those who left this world too soon, with her gut-wrenching performance channeling Anne Hathaway in Les Miz.
