SDL, I agree with some of what you say. When I listen to the radio, top 40, classic rock, pop or whatever, I don't need to feel a CONNECTION to the song. Music is for fun. People like to listen to a good voice, good lyrics or whatever. They're not really looking to CONNECT. Occassionaly you DO hear and singer/voice/song that you emotionally connect to, and that's great, but not really required.
Kris is a singer/songwriter, and Adam is a singer/entertainer. It's simply a matter of preference.
Also, I feel like Adam has shown vulnerability on the stage. Mad World was hauntingly beautiful because he DID connect to the words. They obviously meant something to him, and it showed. Maybe people that are predisposed not to like him didn't see it, but others did. The performance of "One" the other night is not one of my favorites, but again, I really felt that Adam connected with the words.
Kris or Adam in concert? Adam, DEFINITELY.
