These two tributes rely on conceptual gimmickry — the Louvins’ homage is strictly duets; Dolly’s, just womenfolk — with mutually sterling results. Teaming legends ranging from James Taylor to the late Johnny Cash, brotherly ”Lovin”’ is a harmonic feast, even if spotlighting 32 lead vocals on 16 shortish tracks eventually makes the album feel like one big all-star medley. Parton’s even-better paean runs the Shania-to-Sinead gamut, with only Melissa Etheridge’s painful ”I Will Always Love You” misfiring. The ”Woman”liness commences with Alison Krauss making ”9 to 5” into startlingly funky bluegrass and ends with Meshell Ndegeocello turning ”Two Doors Down” into actual funk.
