John Mayer teases Single "Days of Shadow: Listen

John Mayer is back, with his voice intact.

In the first I've heard from fans of singer / songwriter, it passes the throat surgery for grain end of last year, Mayer piece together a new single, "Shadow Day" on your tumblr blog.

With an emphasis on acoustic guitars and lap steel, the song has the climate of the country, while words of hope to direct a comeback: "My days are over, shadow," he sings, perhaps a reference to the clearance received for racially charged comments in the now-infamous Playboy interview.

The new album "Born and raised", initially in October 2011 years before his medical delay, will be released this year, giving the musician the time to pick a few new tricks: "Science lap steel," he wrote in the post in November 2011.
