Personally, Adele is a pop singer, and the recording production values of all her albums (I don't have her last one yet) are for a dedicated audience.
Audiophile recordings they are not. Musically and lyrics are a personal matter; and it reaches each one of us on the level that we chose.
Personally, Adele is not my favorite pop singer. She's nice, with a nice face, voice and style, and without the ultimate emotional wisdom reflecting in my soul.
This is my own personal reflective impression from all her previous albums (three). ...And when I get this one I will return to share some more; my own.
Personally I prefer Amy Winehouse's voice. ...Madonna? ...Her production values are high but her voice lower.
Some female singers that I truly like? ...Let me think about it...and Paula Cole, Laurie Anderson, Eleanor McEvoy, Lucinda Williams, Eva Cassidy, Kasey Chambers, Rickie Lee Jones, Shawn Colvin, Tracy Chapman, Kathleen Edwards, Mary Gauthier, Jennifer Warnes, Sam Phillips, Ani Difranco, Macy Gray, Emmylou Harris, Nanci Griffith, Stacey Earle, Aimee Mann, Joan Osborne, Mary Margaret O'Hara... Just to name few out of my head; there are hundreds more ahead of Adele, in my music book of pop female singers.
That's just me, and my own music exposure and evolution. I love ? them all, Adele included, but her recordings are NOT audiophile. And it's a personal preference about the artist's voice and how it moves us overall. I will get her last one...25 :b
But I highly doubt that she'll make the top 25 of my list.
