I saw Adele perform at the Theatre de la Jeune Lune (my new fav theatre in the minne) last night. For a 20 year old, her voice has amazing depth and personality. Think Amy Winehouse with neither the craziness nor drugs. It's the sort of voice that makes older men reminisce about their teenage years, and young girls giddy about the cute boy sitting next to them.
In other words, definitely check her out. (and don't forget to check out her MPR in-studio performance, which should be updated soon)
