Andy Grammer is a guy out in LA who sounds like the love child of Alicia Keys and Jason Mraz, delivered by Michael Buble. I don't know if that description does him any justice, but his new song "Keep Your Head Up" is a good example of what I mean.
His father is actually a well known children's music artist (Red Grammer).
The personal connection is that I was his counselor at a summer camp maybe 10 years ago and have been following him since. Check it out:
